Grades 3-5 or Adult Emerging Learner

All living things on Earth need water. Everything from people, plants, animals, and even mushrooms and things too small to see need water to survive. Even things like cacti in a desert need some water to live. Water seems to be very important for life. Have you ever looked at a globe – there is a lot of water! Since all living things that we know of need water and many of us want to know if there could be other living things out there beyond Earth, then one thing we can do is investigate places with water beyond Earth. Mars had rivers and lakes of water a long time ago and there could still be some water deep underground there today. Also, there are some moons around other planets that have lots of water. We need to continue to investigate these places and more because if there is water, then there might be life, too.

ESS2.A: Earth Materials and Systems: Rainfall helps to shape the land and affects the types of living things found in a region. Water, ice, wind, living organisms, and gravity break rocks, soils, and sediments into smaller particles and move them around. (4-ESS2-1) *Earth’s major systems are the geosphere (solid and molten rock, soil, and sediments), the hydrosphere (water and ice), the atmosphere (air), and the biosphere (living things, including humans). These systems interact in multiple ways to affect Earth’s surface materials and processes. The ocean supports a variety of ecosystems and organisms, shapes landforms, and influences climate. Winds and clouds in the atmosphere interact with the landforms to determine patterns of weather. (5-ESS2-1)

ESS2.B: Plate Tectonics and Large-Scale System Interactions: The locations of mountain ranges, deep ocean trenches, ocean floor structures, earthquakes, and volcanoes occur in patterns. Most earthquakes and volcanoes occur in bands that are often along the boundaries between continents and oceans. Major mountain chains form inside continents or near their edges. Maps can help locate the different land and water features areas of Earth. (4-ESS2-2)

LS1.C: Organization for Matter and Energy Flow in Organisms: Food provides animals with the materials they need for body repair and growth and the energy they need to maintain body warmth and for motion. (5-PS3-1) *Plants acquire their material for growth chiefly from air and water. (5-LS1-1)

LS2.A: Interdependent Relationships in Ecosystems: The food of almost any kind of animal can be traced back to plants. Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants.

LS2.B: Cycles of Matter and Energy Transfer in Ecosystems: Matter cycles between the air and soil and among plants, animals, and microbes as these organisms live and die. Organisms obtain gases, and water, from the environment, and release waste matter (gas, liquid, or solid) back into the environment. (5-LS2-1)

ESS2.C: The Roles of Water in Earth’s Surface Processes: Nearly all of Earth’s available water is in the ocean. Most freshwater is in glaciers or underground; only a tiny fraction is in streams, lakes, wetlands, and the atmosphere. (5-ESS2-2)

Systems and System Models: A system can be described in terms of its components and their interactions. (5-ESS2-1, 5-ESS3-1)

Big Ideas: All living things on Earth need water. Since water is vital for life on Earth, places beyond Earth that have water are of great interest. In the past, Mars had an abundance of water and it still has water today as do some of the moons around other planets in our solar system. These may be the best places to find life outside of Earth.

One attribute that is common to all living things that we know of is the need for water to survive. Even organisms that live in very dry places need water to live. Why? Why is water so important to living things? One reason that water is so important is because it’s a liquid. This means that it can move around the materials that are needed for chemical reactions. These reactions include the ability for cells to get energy in and to move waste out.

Water is made up of two atoms of hydrogen and one atom of oxygen that make a molecule. But water is a certain type of molecule called a “polar molecule”. Polar molecules have one side of the molecule that’s a bit more positively charged and the other side a little more negatively charged. This allows water to more easily break apart or dissolve other molecules. That’s why you can dissolve salt in water! There are actually a lot of other liquids that can do this but water has other advantages as well. Water is very plentiful. About 70% of the surface of Earth is covered by water, from our oceans and our lakes to our rivers and streams. It turns out that water is also plentiful in the solar system. Comets have a lot of water within them, there is ample evidence that liquid water existed on ancient Mars in great quantities, and many moons have water under their surfaces.

Water is super important for life as we know it! There might be other forms of life out there that don’t rely on water the way we do, but looking for alien life in places with lots of water is one good way to start searching for possible extraterrestrial life.

LS1.C: Organization for Matter and Energy Flow in Organisms: Plants, algae (including phytoplankton), and many microorganisms use the energy from light to make sugars (food) from carbon dioxide from the atmosphere and water through the process of photosynthesis, which also releases oxygen. These sugars can be used immediately or stored for growth or later use. (MS-LS1-6)

PS3.A: Definitions of Energy: The term “heat” as used in everyday language refers both to thermal energy (the motion of atoms or molecules within a substance) and the transfer of that thermal energy from one object to another. In science, heat is used only for this second meaning; it refers to the energy transferred due to the temperature difference between two objects. Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. (MS-PS3-3, MS-PS3-4)

PS3.D: Energy in Chemical Processes and Everyday Life: The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon-based organic molecules and release oxygen.

ESS2.C: The Roles of Water in Earth’s Surface Processes: Water’s movements — both on the land and underground — cause weathering and erosion, which change the land’s surface features and create underground formations. (MS-ESS2-2)

ESS3.A: Natural Resources: Humans depend on Earth’s land, ocean, atmosphere, and biosphere for many different resources. Minerals, fresh water, and biosphere resources are limited, and many are not renewable or replaceable over human lifetimes. (MS-ESS3-1)

Structure and Function: Complex and microscopic structures and systems can be visualized, modeled, and used to describe how their function depends on the relationships among its parts, therefore complex natural structures/systems can be analyzed to determine how they function. (MS-LS1-2)

Big Ideas: All living things on Earth need water. It is critical to cellular function. Since water is vital for life on Earth, places beyond Earth that have water are of great interest. As a polar molecule, it has specific chemical properties, like the ability to dissolve other molecules. Water has been found in other places beyond Earth, like Mars and meteorites. Because water is so universal, astrobiologists look for water on other worlds as an indicator of possible life.

Boundaries: Students in this grade band construct a scientific explanation based on evidence for how the uneven distributions of Earth’s mineral, energy, and groundwater resources are the result of past and current geoscience processes. Emphasis is on how these resources are limited and typically non-renewable. (MS-ESS3-1)

An outstanding curiosity is that in the polar regions, some craters appear to have ‘anomalous reflectivity’ in the shadowed areas of these craters. One interpretation is that this is caused by subsurface ice. The MESSENGER spacecraft hopes to explore this issue in the next few years. In this activity, students measure the surface areas of these potential ice deposits and calculate the volume of water that they imply.

Grades 9-12 or Adult Sophisticated Learner

All life on this planet needs water to survive. Some life can live with very little water in extremely dry places but they still need water. As we strive to find life beyond Earth, it is important to consider what life on Earth tells us about where to look. Why is water so important for life? Water supports cell functions. All organisms are made of cells, from microbes to the largest animals. All of life’s functions are completed within cells. Life needs chemical reactions to take place in order to gain energy, grow, and get rid of waste. Water is a liquid which allows the chemistry of life to take place. It is also a polar molecule which allows most other molecules to be dissolved. Because of this, we call water a “solvent”. Having such a good solvent as water is critical for the functions of life. But there are also some other reasons why water is so important:

Water is plentiful! Hydrogen is the most plentiful element in the universe and oxygen the most plentiful in Earth’s crust. On Earth, about 70% of the surface is covered by water. But there’s also lots of water in other places in our solar system. For instance, we’ve found many lines of evidence that lots of water existed on the surface of Mars during its early times, and Mars currently has a lot of frozen water under its surface. Comets contain mostly water ice. There are lots of moons in our solar system that are made of a lot of water ice, and there are even some moons with liquid water oceans under their icy crusts (like Europa and Enceladus).

Water still has other advantages as a solvent for life. For instance, water stays in the liquid phase over a large range of temperatures compared to some other solvents. That allows more places to have the potential for liquid water. It also has a high heat capacity. This means that water offers some protection to organisms from quick or drastic temperature changes.

Water also has an interesting property with regard to the density of ice. For many molecules, the solid has a higher density than the liquid. So, for most molecules, the solid would sink in the liquid. But this isn’t the case with water. For water, ice is actually less dense than liquid water. This is why ice floats! If this didn’t happen, then all of the organisms that live in the bottoms of lakes in the winter time would be completely frozen. But, even worse, during times in our planet’s history when the world has become very cold (causing what we call Snowball Earth), if frozen water sank, then all of Earth’s ocean life would have become frozen and maybe died!

If we want to understand how life works, then it’s really important to understand the chemistry of water. And astrobiologists who are wondering if we’re alone in the universe need to be aware of the potential for water to be important for other kinds of life as well. Right now, we’re investigating worlds like Enceladus and Europa, Mars, and other solar system bodies that show signs of water. Also, beyond our solar system, we’re looking for exoplanets that have the potential for liquid water at their surfaces, since they might be important places for us to look for possible extraterrestrial life.

PS3.A: Definitions of Energy: Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed. (MS-PS3-1) ▪A system of objects may also contain stored (potential) energy, depending on their relative positions. (MS-PS3-2) Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. (MS-PS3-3, MS-PS3-4)

LS2.C: Ecosystem Dynamics, Functioning, and Resilience: Biodiversity describes the variety of species found in Earth’s terrestrial and oceanic ecosystems. The completeness or integrity of an ecosystem’s biodiversity is often used as a measure of its health. (MS-LS2-5)

ESS2.A: Earth’s Materials and Systems: All Earth processes are the result of energy flowing and matter cycling within and among the planet’s systems. This energy is derived from the Sun and Earth’s hot interior. The energy that flows and matter that cycles produce chemical and physical changes in Earth’s materials and living organisms. (MS-ESS2-1)

ESS2.C: The Roles of Water in Earth’s Surface Processes: Water continually cycles among land, ocean, and atmosphere via transpiration, evaporation, condensation and crystallization, and precipitation, as well as downhill flows on land. (MS-ESS2-4) ▪ Global movements of water and its changes in form are propelled by sunlight and gravity. (MS-ESS2-4)

ESS2.D: Weather and Climate: Weather and climate are influenced by interactions involving sunlight, the ocean, the atmosphere, ice, landforms, and living things. These interactions vary with latitude, altitude, and local and regional geography, all of which can affect oceanic and atmospheric flow patterns. (MS-ESS2-6) The ocean exerts a major influence on weather and climate by absorbing energy from the Sun, releasing it over time, and globally redistributing it through ocean currents. (MS-ESS2-6)

Stability and Change: Much of science deals with constructing explanations of how things change and how they remain stable. (HS-ESS2-7)

Big Ideas: All living things need water. Water is critical to cellular function, chemical reactions, and thermal regulation. Water is less dense when a solid and stays in the same state over a wide temperature range. It is abundant on Earth and a common thread between all living things. Water has been found in other places beyond Earth, like Mars and meteorites. Because water is so universal, Astrobiologist look for water on the surface and atmosphere of exoplanets as an indicator that the planet could support life. Understanding the chemistry of water is important to understanding how life works.

Boundaries: In this grade band, students investigate the properties of water and its effects on Earth materials and surface processes including chemical investigations like chemical weathering and recrystallization. (HS-ESS2-5)

Storyline Extensions

Water is so cool.

The range of temperatures at which water stays liquid is rather large compared to most other common solvents. For instance, at sea level methane freezes at -182 Celsius © and boils at -162 C (a range of 21 C) and ammonia freezes at -78 C and boils at -34 C (a range of 44 C), meanwhile water freezes at 0 C and boils at 100 C (a range of 100 C). This means that the range of temperatures where water is liquid is more than twice that of ammonia and almost five times more than that of methane.

Water has a high surface tension. This means that that the molecules at the surface of a body of water are attracted to each other and hold each other together. You can see this yourself by filling a glass with water to the very tippy top and then seeing how many more drops of water you can get into it. You’ll be surprised to find that you can actually get a good bit more water into the glass! The high surface tension of water is also why some insects, like water striders, are able to move around on top of water without sinking into it. It also is related to something called “capillary action”, which is used by many plants to draw water up from the ground against gravity.

It’s actually really rare for a solvent to be more dense as a liquid than as a solid. We know of other elements and molecules that are more dense as liquids, but it’s far more common for the solid form of a substance to be more dense.

[note: this is fairly advanced] Oxygen is a member of the group of elements known as the “oxygen family” (also sometimes called the chalcogens). These are the elements in the periodic table that are in group 16 (the vertical column starting with oxygen and going down). They include oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po). All of these elements can form bonds with two hydrogen atoms. However, none of the other chalcogens come close to oxygen in its large range of temperatures where it is a liquid. This is because oxygen is much more electronegative (much greedier for electrons) and makes a far more polar molecule than the others. This greater polarity leads to stronger hydrogen bonding and the greater range of temperatures for liquid water.

The water was crystal clear, and the colours of the fish and coral were so vibrant and beautiful. After snorkelling, we stopped at a small beachside restaurant for lunch, where we enjoyed fresh seafood and cold drinks while watching the waves roll in. It was a memorable day, and I will always cherish the time I spent in the water on that trip. This trip reminded me that one of my best memories was only possible because water exists. It showed me the life that water holds below land, like coral reefs and also how beautiful animals exist, like turtles.

Water: The Element of Life Essay

Introduction, ancient time, works cited.

The availability of water on the Earth is said to be the reason the planet can sustain life. This simple substance is the combined need of all living things and it covers the major portion of the planet as well. Its uses include drinking to quench thirst, irrigation to support food production, as an agent to put out fire, sewage disposal, and uses of a more modern nature such as for rotating thermal turbines for power generation and recreational purposes. It was aptly termed by some Greek philosophers to be the source of all existence. Thus in the modern world, as it was in ancient, water remains an important natural resource without which humans can not survive.

The ancient civilizations of Mesopotamia and Egypt realized the importance of water as they were able to build great cities and develop around sources of water such as the Tigris and Euphrates as well as the Nile. It served as a source of fresh drinking water and the periodic flooding across the deltas allowed plentiful harvests to be had multiple times a year which allowed a large urban population to be supported. The Mesopotamians were able to control the rivers via the construction of irrigations dikes and other types of waterworks (Mays, p. 102). This made the flatlands where food was produced due to plentiful water, a source of conflict among tribes. When water works became decrepit, tribes attacked to get hold of scarce food commodities, whereas otherwise, peace was able to be sustained in the region.

The Egyptians were fortunate in that they had a more predictable river in the form of the Nile which wrought less destruction via flooding. They were also able to manage their water resource through a technique called basin irrigation (Mays, p. 156). This involved constructing a network of ditches or basins near the river where flood water was directed and allowed to stay for an amount of time, making the soil fertile after which plantation could begin, siphoning the water off to other basins. Technological developments aimed at collecting water from the river also kept coming such as the “shaduf” which was a rudimentary wooden water-lifting device, and the “noria” which was an early water wheel (Mays, p. 178). Although the water was crucial, it was available in substantial amounts and was not a matter of contention, with decision-making and distribution rights being a matter for the farmers to deliberate while the state kept away from it (Fiero, p. 26). There also has been little evidence of a law decreeing the prescribed way of water management which confirms the control over demand of the resource at the time.

In the modern age, however, with burgeoning populations, water demand is not only large but growing. There are also plenty more uses for the natural resource which requires water management to be moderated at the state level. The national and local governments have a very important role to play in this regard. Comprehensive strategies for water management need to be developed to handle the resource. This should be aimed at reducing demand by encouraging plantation of less water-absorbing crops and developing an efficient irrigation system so that the available water is not wasted. Campaigns for public awareness could be launched at the local government level which could also address the problem of alien plants that use water and leakages that waste the resource. New water resources could also be explored such as by drilling underground. At the national level, optimal use of the river systems should be made via the development of dams and canals so that adequate storage of the available water can be carried out. There is also a need to work with other nations at a global level to improve the laws about water use and rights so that international conflicts over the resource do not develop. The world is already seeing wars being waged for a crucial resource such as oil which is not even necessary for sustaining life. If the water becomes the object of a similar conflict, it could prove to be much more disastrous considering its importance for humans.

Water means Life. Water is a prime natural resource. It is a basic need for humans and a precious asset that living beings have. Water is equally vital for the survival of the plant and animal kingdoms. Soil needs water for sustaining plants. The water cycle is essential for ecological balance too. Though a big portion of the Earth is covered with water, only a small portion of it can be used for various human activities. So we need to be judicious and rational, regarding the usage of water.

Why is water important for our bodies?

Water is important for our body for the following reasons.

Above 70% of our body contains water so it is pivotal for the human race to survive.

Water helps in regulating our body temperature.

Water helps in the digestion of solid food.

It also keeps our skin healthy and hydrated.

Water helps in excreting waste from our body through sweat, urination, and defecation. So replenishing the water in our body is essential to prevent dehydration.

Drinking water also helps in reducing calories and maintaining body weight because it can increase the rate of metabolism.

Water consumption lubricates the joints, spinal cord, and tissues.

Importance of Water

All living organisms, plants, animals, and human beings contain water. Almost 70% of our body is made up of water. Our body gets water from the liquids we drink and the food we eat. Nobody can survive without water for more than a week. All plants will die if they do not get water. This would lead to the death of all the animals that depend on plants for their food. So the existence of life would come to an end.

Role of Water In Life Processes

Water plays an important role in most of the life processes by acting as a solvent. The absorption of food in our body takes place in solution form with water as the solvent. Also, many waste products are excreted in the form of solutions through urine and perspiration.

Water helps in regulating our body temperature. In hot weather, we drink a lot of water. This maintains our body temperature. Also, water evaporates from the surface of our body as sweat. This takes away heat and cools the body.

Water is essential for plants to grow. Plants need water to prepare food. They also absorb dissolved nutrients from the soil through their roots.

Aquatic plants and animals use the nutrients and oxygen dissolved in water for their survival.

Uses of Water In Everyday Life

Water is used for drinking, washing, cooking, bathing, cleaning, in our day-to-day life.

It is used to generate electricity in hydroelectric power stations.

Water is used for irrigating fields and in the manufacture of various products.

Other Uses of Water

Water serves as a means of transportation for goods and people.

It provides a medium for recreational sports such as swimming, boating, and water skiing.

Water is also used to extinguish fires.

Importance of Oceans

Oceans are of immense use to man. They are useful in many ways, directly and indirectly. They not only play a significant role in the climate of adjoining countries but also serve mankind in many ways. They are a storehouse of several resources.

An ocean is a major source of water and forms a major part of the water cycle. Oceans contribute water vapor to the atmosphere and we get the same in the form of precipitation.

The oceans are the biggest storehouse of edible forms of marine food, fish being most important. In addition to food, sea animals provide other products like oil, glue, etc.

Oceans have enormous mineral and chemical wealth. A variety of dissolved salts like sodium chloride (common salt), magnesium chloride, and potassium chloride are found in plenty in the oceans.

Oil and gas are important fuels obtained from oceans.

Importance of Lakes and Rivers

Economic and industrial development

Water storage

Hydroelectric power generation

Agricultural purposes

Modern multipurpose dams

Source of food

Source of minerals

Tourist attractions and health resorts

Rivers provide fresh drinking water

Ports can be built on them as they form good natural harbors

Major Concerns

Although our planet Earth is covered with 71% percent of water and 29% of the land, the fast-growing contamination of water is affecting both humans as well as marine life. The unequal distribution of water on the Earth and its increasing demand due to the increasing population is becoming a concern for all.

Water pollution makes it difficult for marine animals to sustain themselves.

Covering over 71% of Earth’s surface, water is undoubtedly the most precious natural resource that exists on our planet. Without the seemingly invaluable compound comprising Hydrogen and Oxygen, life on Earth would be non-existent.

We are slowly but harming our planet at a very alarming rate.

Characteristics of a Good Essay.

It must be brief: As pointed out earlier, a good essay must be short, and also to the point. So, if students are writing an essay on the importance of water it must only deal with the water, and anything which does not directly serve the purpose must be excluded.

Must cover the whole topic: Though it may seem a little contradicting to the first point, what is meant by covering the whole topic is that the maximum number of aspects dealing with the importance of water must be covered in this essay. For instance, water is important for all living organisms and not just humans, and so the same has to be covered in one or the other way in the essay on the importance of the water.

Must be to the point: The essay must remain true to the central idea of the topic, which is the importance of water in this case. Hence, almost all the sentences written in the essay must serve the main topic in one or another way. And also, writing should not be vague or ambiguous, or illogical.

Human beings should realize how important and precious water is. At the individual level, you can be more responsible and avoid wasting water so that our future generation can make the best use of this natural resource abundantly.

250 Words Essay on Water Is Life

Introduction.

Water, a simple molecule composed of two hydrogen atoms and one oxygen atom, is the lifeblood of our planet. It is the most abundant and essential resource, without which life as we know it would not exist.

The Essence of Life

Water is the fundamental building block of life. It is involved in every bodily function, from digestion and circulation to temperature regulation and waste removal. The human body is approximately 60% water, reflecting its importance in maintaining life and health.

Water and the Environment

Water’s role extends beyond the individual organism. It is integral to maintaining Earth’s delicate ecosystems. Water cycles through our environment, from the atmosphere to the earth and back again, supporting plant and animal life, shaping landscapes, and influencing climate patterns.

The Social and Economic Impact of Water

Water also plays a significant role in social and economic structures. It is vital for agriculture, industry, and energy production. Access to clean water is a determinant of societal health and prosperity. Yet, water scarcity, pollution, and mismanagement pose major challenges, with profound implications for human rights, social equity, and global stability.

In conclusion, water is life. It is the essence of biological function, the driver of ecological systems, and the underpinning of social and economic structures. As we face a future of increasing water scarcity and pollution, understanding and respecting the critical role of water is more important than ever. We must strive to conserve and protect this invaluable resource, for it is not just water, but life itself.

500 Words Essay on Water Is Life

The essence of life: water.

Water, the most vital natural resource, is the lifeblood of every living organism on Earth. From microscopic organisms to the largest mammals, all life forms depend on water for survival. This universal solvent, often referred to as the “elixir of life,” performs essential roles in biological processes, climatic regulation, and economic development.

Water: The Biological Imperative

Water is crucial to the existence and sustenance of life on Earth. It comprises about 60-70% of a human body, acting as a medium for biochemical reactions, a transporter of nutrients and waste, and a temperature regulator. It is the primary component of cells, tissues, and organs, and without it, life as we know it would cease to exist.

In the plant kingdom, water is instrumental for photosynthesis, the process by which plants produce food. It also facilitates the transportation of nutrients from the roots to other parts of the plant. Hence, the absence of water would disrupt the food chain, leading to catastrophic effects on all life forms.

Water and Climate

Water plays a significant role in regulating Earth’s climate. The hydrological cycle, involving evaporation, condensation, precipitation, and runoff, is a key driver of weather patterns. Oceans, which hold about 97% of Earth’s water, absorb heat from the sun and distribute it around the globe through ocean currents, thereby moderating global temperatures.

Furthermore, water in the form of ice at the poles and high altitudes reflects sunlight back into space, helping to stabilize Earth’s temperature. The melting of this ice due to global warming is a cause for concern as it could lead to a rise in sea levels and drastic changes in climate.

Economic Importance of Water

Water is indispensable for economic development. It is essential for agriculture, which is the primary source of livelihood for a large portion of the global population. Industries such as power generation, manufacturing, and tourism also rely heavily on water. Moreover, waterways serve as important routes for trade and transportation, contributing significantly to the global economy.

Water Scarcity and Conservation

Despite its abundance, water scarcity is a pressing issue in many parts of the world due to factors like overpopulation, overexploitation, pollution, and climate change. This underscores the need for efficient water management and conservation.

Water conservation can be achieved through strategies like rainwater harvesting, recycling and reusing wastewater, and adopting water-efficient technologies. It is also crucial to create awareness about the importance of water and the need for its conservation.

In conclusion, water is not just a life-sustaining resource but the very essence of life. It is a critical component of biological processes, a key climate regulator, and an economic catalyst. However, the growing water scarcity necessitates urgent action to conserve and manage this invaluable resource. As we recognize water’s integral role in our lives, it becomes our collective responsibility to ensure its availability for future generations. After all, water is life.

Water — the universe is full of it. But only Earth transformed into a blue planet. Water is the source of life, but also a constant threat. An essay about the precious asset of water.

Dr Torsten Meise is a freelance journalist and writes for publications including "Stern", "Mare" and "Spiegel". He focuses on the areas of energy, science and technology.

"Oh, my God, look at that!" was Bill Anders' response on Christmas Eve in 1968. Because as he looked out of the window, he saw something that no human had ever seen before: the Earth rising over the moon's horizon. A blue dot in space, half covered in shadow. Apollo 8 was the first space capsule to orbit the moon. The flight was perfectly planned, but the space mission's photographer hadn't expected this motif, which has gone down in history titled "Earthrise".

The fact that Bill Anders pressed the shutter release button of the only Hasselblad camera on board with colour film forever changed the way we see the Earth. Our radiant blue home planet made an impression on humanity's collective consciousness.

Many people see "Earthrise" as the beginning of the environmental movement. The motif from Apollo 8, Magazine 14/B is frequently described as what may be the most influential environmental photograph in history. Also because no image had ever before shown so clearly and succinctly what makes Earth so unique: a seemingly endless mass of water.

However, pictures can also be misleading. If the Earth was a basketball, all its water would fit in a ping-pong ball. All available freshwater resources would be no larger than a kernel of popcorn. And if the Earth's water were a bathtub, the accessible drinking water would fit in a shot glass. Freshwater reserves only represent 2.53 per cent of the water on Earth. And only 0.3 per cent can be tapped into for drinking water.

Together with two scientists from the United States, Adam Nieman und Howard Perlman, Jack Cook from the Woods Hole Oceanographic Institution set out to represent the planet's known water masses in an illustration. It shows the Earth without water; next to it hovers a blue ball that represents all the water on Earth — about 1.3 billion cubic kilometres. It's so small that it's easy to think that the illustration is fake. But it's accurate.

Oceans, lakes and rivers may cover over 70 per cent of the globe but, compared to the mass of rock and other materials, water only makes up a very small part due to the relatively shallow depth of these bodies of water. The illustration also shows the potentially accessible freshwater reserves necessary to sustain life for people, animals and plants: the kernel of popcorn. Two thirds of the Earth's freshwater are trapped in glaciers and polar regions and are not included here. That's all there is to keep 7.5 billion people alive. Will it be enough in the long run?

It's easy to get completely lost in thought when contemplating water. It has made everything possible on Earth. It surrounds us, is in us, with us and for us, wherever we look. There are traces of water everywhere in the universe. It is the only compound on Earth that exists naturally in all three physical states: as ice, gas and liquid.

The fact that all life comes from water is general knowledge. Before birth, the human embryo swims in a liquid similar to sea water. Up to 96 per cent of this liquid is water. Children's bodies are about 70 per cent water. Over the course of a lifetime, the body dehydrates to about 50 per cent. But one truth always remains: no process in the human body would be able to take place without liquid, without H₂O. All cells consist mainly of water. Transport of nutrients and waste, the circulatory system, glands, lungs, joints, eyes — nothing in the human body functions without water.

The flood is omnipresent

Water, this miracle substance, inspires the imagination and quenches our thirst for knowledge. Thales of Miletus, the famed "Astrologer who Fell into a Well" while gazing into the heavens, established the age of scientific philosophy around 2600 years ago, despite his clumsiness. Because the philosopher did not leave behind any written work, we can only speculate when and how he came to believe that all life had its origin in water. Perhaps outside his own front door, while looking into the lovely Ionian Sea. Or maybe at the damp bottom of the well.

His intuition was right. And he wasn't far off from the great world religions, which all give water key significance during the creation of humanity and Nature. And it's hardly surprising.

Human life is inextricably linked with water. It is vital. Ten thousand years ago, when our ancestors ended their nomadic existence to create settlements, they settled where freshwater was available: by rivers and lakes. And water thus became the most important player in the drama of survival. Because rivers can dry up or flood their banks if the cycle of condensation and precipitation falls out of sync.

Droughts and floods are among humanity's primal fears, and stories of these events can be found in nearly all the world's religions. The very first written records from early civilisations in Mesopotamia focus on the Flood. The Sumerian epics were integrated into the ideas contained in the Jewish, Christian and Islamic Genesis traditions. Mythologies from India, China and even indigenous peoples in the Americas also contain their own Flood narratives.

Water means power

A few years ago, Roman Polanski's movie "Chinatown" (1974) was selected as the best crime film of all time by British critics. In it, speculator Noah Cross, played by John Huston, redirects water away from the farms surrounding Los Angeles. Then he purchases the land at a cheaper price and waits for the growing city to buy it from him for inflated prices. The screenplay was originally titled "Water and Power", based on the California Water Wars, a series of conflicts in the early 20th century that led to corruption, crime and the decline of entire valleys in the area surrounding the Hollywood dream factory. The issue of water is still critical in California today.

Since 2011, a drought has depressed the region, which is not only home to Hollywood, but also to Silicon Valley. The interests of cities, farmers and corporations continually clash here. The "New York Times" recently reported about the small town of Weed in Northern California. A lumber company claims the spring that provides the town's drinking water as their property and now wants to sell the water to a bottled water company. The residents of Weed were told to find another water source. However, the US has some of the most abundant water resources in the world, so water should not actually be a problem. Actually.

California is everywhere. Even Hamburg is at loggerheads with Nordheide because of water. "Water Wars" has become a term for the series of conflicts that are simmering around the world. Reports of conflicts are becoming more frequent: between India and Pakistan, Tajikistan and Kazakhstan, Uzbekistan and Turkmenistan, Jordan and Saudi Arabia, and in many other regions of the world. For the most part they are still cold wars and, fortunately, have not yet fully unleashed their dangerous potential. Even in 1985, UN Secretary General Boutros Boutros-Ghali predicted that "the next war in the Middle East will be fought over water, not politics." As we know, this prediction was not correct, but that doesn't mean that the general prognosis is wrong.

Drinking water as a fundamental right

When detective J.J. Gittes (Jack Nicholson) asks villain Noah Cross in "Chinatown" what his motivation is behind the crimes, the answer is: "The future, Mr Gittes, the future!" Drinkable water is the future. And it is a scarce resource on the blue planet. According to UNICEF and the World Health Organization (WHO) , 663 million people currently do not have access to clean sources of drinking water and 2.5 billion people do not have access to appropriate sanitation. The resulting diseases kill more children than malaria, measles and AIDS combined. The lack of water not only fans conflicts, it also causes potential to lie dormant that is needed to create a better world.

The United Nations estimates that women worldwide spend more than 40 billion hours gathering water. Countless girls do not attend school in the poorest countries because they spend the entire day searching for water. What a waste. The United Nations adopted Resolution 64/292 in 2010, which recognised "the human right to water and sanitation and acknowledged that clean drinking water and sanitation are essential to the realisation of all human rights".

The UN decision will have long-term effects and ensure more involvement from the global community. According to the German Federal Government, investing one euro in this area can increase the gross domestic product in developing countries by eight euros. By the way, when it comes to drinking water, a great deal has already happened. According to estimates from UNICEF, 91 per cent of all people have access to clean water today; that's 2.6 billion more than in 1990.

But just when there is a spark of hope, another danger is already looming: climate change. As the ice cover in Greenland and the Antarctic melts, and the water spreads throughout the warming oceans, the sea level is rising irreversibly. And it is threatening the places where the most people live, the largest megalopolises on the coasts: New York, Los Angeles, Rio, Mumbai, Shanghai, Hong Kong, Tokyo, Sydney, Lagos, Jakarta, Singapore and many others.

Since the beginning of the 20th century, the sea level has already risen 20 centimetres. The risk of losing large sections of densely populated coastline to the ocean in certain corridors has been projected. According to the Intergovernmental Panel on Climate Change, the sea level is rising with increasing speed. It is currently rising at over three millimetres per year, more than twice as fast as at the beginning of the 20th century. That is a flood in slow motion, one with a message.

Has a new age begun?

Because humanity has learned to survive droughts and floods, there is an illusion that a world emancipated from its natural conditions, or from its "well", has developed. Scientists are currently involved in a heated debate about whether we have already entered a new geological era, the Anthropocene.

The "human age" is characterised by the fact that changes on the planet are no longer driven by natural influences like wind and water; Instead they are driven by human activities. This includes pollution and management of rivers, construction of irrigation canals across hundreds of kilometres, consumption of ground water resources and aquifers, vast urbanisation and the associated infrastructure, and finally, climate change as well, with the loss of glaciers and coastal regions.

For Germany, the largest problem is anthropogenic pollution of ground water — with nitrates in a third of the Federal Republic and the legacy of the mining industry in the Ruhr area. While civilisation has moulded the planet little by little, water has been and will continue to remain a critical aspect throughout the ages. It remains the medium of existence and potential, but also a catalyst for discovery and a constant reminder of how perilous life is. Or, as Bill Anders said: "Oh, my God, look at that!"

Need to Save Water

Currently, there are many regions in the world that are facing extreme water scarcity due to deÃ§line of groundwater and scanty rainfalls. Also, in some areas, the groundwater is contaminated or it has been overused. Thus, these factors have to lead to drought situations and in these areas it has lead to water scarcity. Furthermore, urbanization and industrialization have added to the problems where groundwater has been overused to fulfill the increasing demands of the population.

According to the WHO report, 1 out of people does not have access to safe drinking water. Seeing this, the water crisis in the future does seem inevitable. Also, it calls for an immediate action plan in order to conserve water so that precious resource can be saved for today as well for future generations.

Save Water Initiative

This initiative can help and promote the conservation of water . Also, it can be spread awareness among the people about the importance of water. Additionally, the save water campaign helps people realize that the sources of fresh and pure water are very limited. So, if it is overused that there are chances that they might not be able to fulfill the increasing demands of the population. Through this campaign, we can create awareness among the people about the benefits and preserving water and using it diligently.

Water Is The Source Of Life

Water is the most essential source for the life of human beings, animals, and plants, also it is a major stream in utility system and probably the most widely used raw material in process industries. Being an efficient technology for saving freshwater and reducing wastewater. In 1980, Takama and coworkers (1980) addressed an approach for optimal water allocation in a petroleum refinery based on a superstructure of all possible re-use and regeneration opportunities. Then in 1989, El-Halwagi and Manousiouthakis (1989) defined the composite curve to denote mass exchange operation, which was adapted from the methodology developed for heat exchanger networks by Linnhoff and Hindmarsh.

Remarkable work was done by Wang and Smith (1994a) by introducing the important concepts of water pinch and limiting water profile, which is further improved later.

The graphical method can give the minimum fresh water requirement of the entire process in a direct way, but when multiple contaminants are present, graphical methods require assumptions for ease of implementation, some of which may be difficult to justify.

Huang and coworkers presented a mathematical programming solution of the combined problem of water allocation and treatment by solving nonlinear problem (NLP). Recently, Bagajewicz and Savelski showed how to reduce a nonlinear program to a linear program (LP), by inserting the maximum outlet concentration conditions. The mathematical programming methods are effective in optimizing large-scale systems but can be difficult to interpret, giving designers fewer insights compared with graphical methods. Works by others are also in the two kinds.

Water networks mentioned above are designed using strategies similar to those used in the design of networks of heat exchangers, with pipes connecting the unit processes.

“ Ok, let me say I’m extremely satisfy with the result while it was a last minute thing. I really enjoy the effort put in. ”

When the entire plant involves only a few processes, the networks are simple and water savings at or near the maximum are achieved. However, for a large petrochemical or chemical complex, with many unit processes, the piping network becomes very complicated and hard to design and control. Moreover, the change of water flow rate or water quantity in one unit process will influence other unit processes. If using freshwater to adjust the change, the water-saving effect will decrease. To solve the problem, Feng and Seider (2001) introduced a new structure and its design methodology for water networks. The new structure uses one or more internal water mains (or reservoirs) to simplify the network. These water mains simplify operation and the control of water quality, as well as the design strategy. However, their work involved only single contaminant.

Design methodology for water networks with internal water mains H, Ma, X. Fenf_and K. Cau, ” A Rule-based methodology for water network with internal water mains 2007, Zhi- Yong Liu, Yi Yang, Lin-Zhan Wan, Xi Wang and Kai- Hu, ” A heuristic design procedure for water-using networks with multiple contaminants 2009a, He, H.N.; Wan, L.Z.; Liu, Z.Y. A simple design for water network with multi-contaminant internal water mains. CIESC Journal, 2010[19], Xiao Yanfan, Yan Pengli, Zhi Yongliu, Chun Hui Panb.

A new Design Method for Water Using Net Work of Multiple Contaminants with Single Inter Water Main, Journal of Cleaner Production, 2012.

Recycling for Water Networks with Internal Water Mains by Using Concentration Potential Concepts. Chemical Engineering Science, 2013. When dealing with the multiple contaminant problems, the design methodology for single contaminant cannot be used anymore. In multiple contaminant system, the key contaminant of each unit is different which is related to the water source to the unit. Therefore, the inlet and outlet flow rate allocation of each unit is difficult to specify because its freshwater consumption is close related to the choice of its sources. Due to the complexity, the design for water networks with single contaminants based on internal mains cannot be extended to that of multiple contaminant systems. In this paper, the design methodology for multiple contaminant systems is presented. Emphasis on the location of the first internal water main. Generally, water networks having just one internal main determined by the presented method can obviously reduce water consumption, approaching the minimum value.

Short Essay on Importance of Water (200 words)

Water is available in abundance on Earth. It is present on the surface of Earth as well as beneath it. The water bodies present on Earth’s surface include rivers, ponds, seas and oceans. The surface water evaporates due to the excessive heat of Sun. It is circulated in the atmosphere and forms clouds that burst and reach the Earth’s surface in the form of rain. Thus, the water that evaporates gets replenished by the natural process of water cycle which occurs continuously. This helps in maintaining the eco system and makes our planet worth living.

While Earth is filled with plenty of water, fresh water is very small part of it and its amount is only decreasing by the day. It is sad but true that due to various human activities and human negligence, the water present on Earth is getting polluted. Fresh water is getting depleted as the water bodies are being polluted due to industrial as well as domestic waste.

It is high time we must understand the importance of water in our lives and the necessity to save it. There are many simple ways in which we can avoid wastage of water such as bathing with less water, watering plants with waste water from RO, cleaning the car with a wet cloth rather than pipe, etc. We must also use the method of rain water harvesting to collect rain water. This way we can contribute our bit to save water.

Essay on Important Uses of Water (300 words)

Introduction.

Water is available in abundance on Earth. It is one of the main reasons which make life possible on our planet. Available from different sources, water is an essential requirement for all the living beings. It is used for various purposes by human beings. Here are some of the important uses of water.

Different Uses of Water

Drinking: Drinking water is vital for the survival of living beings. So, one of the main uses of water is drinking.
Cooking: Water is also used for the purpose of cooking. Many recipes such as lentils, rice, soups, etc require water. Besides, even the vegetables and fruits that do not require added water for preparation need to be washed thoroughly before eating/ cooking.
Cleaning: Whether it is cleaning a house, office, car, machinery or anything for that matter, it is not possible without using water. All the cleaning tasks require water.
Washing: Water is also required for the purpose of washing clothes, utensils and various other things.
Sanitation: Water is also required for the purpose of sanitation. It helps in maintaining cleanliness and hygiene.
Agriculture: A major share of water on Earth is used for the purpose of agriculture. It mainly used for irrigating the farms to keep the land fertile and ensure adequate supply to the crops. It also used for rearing the livestock.
Industries: Industries use water for various purposes. The manufacturing of many products require water. It used in the transportation, fabrication and processing of various products. Some of the industries that need good amount of water include pulp and paper and engineering industries.

Water used for different purposes in homes and offices. It is as much essential for other living beings as it is for the humans. Therefore it is one of the main reasons we are alive. Is impossible to imagine life without water.

Essay on Importance of Water: Water Cycle (400 words)

Water is present in solid, liquid and gaseous forms on Earth. All three forms of water are essential to maintain our planet’s ecological balance. Water is in high demand as it used for various purposes. Fortunately, we have many sources of water including seas, rivers, oceans and rain. Water replenishes itself naturally and constantly by way of water cycle thereby maintaining balance in the atmosphere.

Why is Water Cycle Important?

Water needed for the survival of the living beings. Be it plants, animals or human beings – all three require water. While plants and animals mainly require water for the purpose of drinking or as habitat, human beings use water for several purposes. Water would have long vanished from the face of Earth if the process of water cycle hasn’t existed.

The process of water cycle involves different steps. These are evaporation, transpiration, condensation, precipitation and surface run off. Water evaporates from different sources including oceans, seas and rivers due to sun’s heat. Water vapours rise into the atmosphere. Slowly these vapours cool down and condense to form clouds.

When large amount of vapours join together, the cloud becomes heavier and falls in the form of rain. This way the water falls back on the surface of Earth. It gets accumulated in rivers, lakes, oceans, layers of rocks and soil. This completes the process of water cycle. The water collected in oceans and other water bodies once again evaporates and the entire cycle reoccurs. This is an ongoing process. Water cycle also impacts the weather condition on Earth. The cycling of water in the atmosphere regulates the weather patterns.

Important Sources of Water

Sources of water have broadly divided into two categories:

Surface Water: This found in rivers, lakes, streams, seas, oceans and also reservoirs. The downpour from the clouds and the melting of snow from the mountains fill the rivers and the lakes. Rivers flow continually and also meet the sea. The sea water flows into the ocean. Surface water evaporates and enables the water cycle process.
Ground Water: Ground water is present under the Earth’s surface. Water seeps under the land via porous rocks and soil. This water gets stored under the Earth’s surface and extracted by digging wells and also constructing tube wells.

Water cycle makes sure the lost water replenished on the planet and is available in abundance for all the living beings. If this process did not occur naturally we would not have sufficient water on our planet.

Essay on Importance of Water – An Essential Part of Our Life (500 words)

Water is an essential part of our ecological system. It is one of the main substances that make our planet fit for living. Water is essential for the growth and development of plants and animals. However we use water directly as well as indirectly for many of our needs.

Water – An Essential Part of the Human Body

Research shows that up to 60% of the human body made of water. Our lungs are around 83% water, our muscles and kidneys are 79% water, our brain and heart are 73% water, our skin contains 64% water and our bones have 31% water. Water helps in several functions of the body including blood circulation, digestion, regulating body temperature, protecting tissues and joints and also excreting waste via perspiration, defecation and urination.

Our body continually uses water to perform these functions. So, we need to provide a continuous supply of water to our body to help it function well. It is important to replenish the lost water timely.

Water – Vital for Plant Growth

Plants prepare their food by way of photosynthesis. Water forms an essential part of this process. As we water the plants, it enters their stem and moves up to their leaves. However it draws nutrients from the soil and carries them to the leaves. Photosynthesis takes place in the leaves. The water present in the leaves evaporates and exchanged for carbon dioxide.

Without proper supply of water, the plants do not get enough nutrients and photosynthesis cannot take place. As a result, the plants begin to droop and fall. Different kinds of plants require different amount of water at different times. While some plants need to watered twice a day others require water once a week while there are yet others that can go weeks without water especially during cold and moist season.

Water – Habitat for Marine Creatures

Water serves as home for the marine creatures. Wide variety of fishes, turtles, frogs, crabs and other marine creatures live in seas, oceans and rivers. These water bodies are their habitat. Most marine creatures live solely in water and cannot survive on land. They add to the biodiversity and also are an essential part of the eco system.

The increase in the level of water pollution is causing a threat to these beautiful and innocent creatures. Many species of the beautiful marine creatures have either gone extinct or endangered. Water pollution caused due to various human activities. It needs to controlled in order to provide a safe and healthy habitat for the marine creatures.

Water is vital to the survival of living beings. Even as water recycles naturally, the amount of fresh water on Earth is depleting fast. This is all because of the negligence of human beings. We use water for several purposes throughout the day. But we aren’t using it efficiently. We waste it more than we use it. This is the reason why water is decreasing at a rapid speed. It is high time we must use water wisely and limit the activities that pollute it.

Long Essay on Importance of Water (600 words)

Water is among the most essential substances on Earth. Two third of Earth covered with water; however, only a small part of it fresh water which is fit for human use. The growing pollution is polluting the fresh water too, thereby making it unfit for any kind of use. Besides, fresh water available for use often wasted during various activities. This has become a global cause of concern. It is time we should understand the importance of water and also try to save it.

Conversation of Water

In this era of growing water pollution, we need to watch out our activities. Fresh water is getting scanty mainly due to two reasons. One of these is the increasing level of water pollution caused due to industrial waste and various other human activities and the other is the continuous wastage of water by people around the world.

We must conserve water otherwise it will become difficult for us to survive on Earth in the times to come. Water is essential to maintain the ecological balance and create an atmosphere which is appropriate for us to survive. It also needed for drinking, cooking, cleaning, irrigating the fields and various other activities. We need to save water and put it to correct use.

Methods to Conserve Water

There are many ways in which we can conserve water. Several activities that we indulge in our daily lives can done differently to save water. Here is a look at these:

We often keep the tap on while we brush our teeth. This results in a lot of wastage of water. Turn the tap on only when you require it, else keep it off. A lot of water that goes down the drain unnecessarily will saved this way. Practice the same while washing your hands as well.
It is best to use bucket while bathing as a lot of water wasted while taking shower. Or you can keep a tub under the shower when you don’t require water while taking shower. This water can used for watering the plants or flushing.
The waste water from RO can collected in a bucket and used to water the plants or for cleaning purpose. You can also do the same with the water left after boiling potatoes, noodles and pasta. This water is hot and can very well used for cleaning oily and greasy utensils.
Water the plants during evening or early morning hours so that the water absorbed properly and does not get evaporated fast. This way you will require less water for watering the plants.
Do not make use of water to defrost food items.
Instead of using a pipe to wash your car, it suggested to use a bucket and wet cloth. You can also get it washed regularly from a car wash service that uses recycled water for this purpose.
Rainwater harvesting is a good way to store water and to put it to good use.
Install water efficient appliances such as low flow bathroom fixtures, sink systems, dish washers and washing machines and use them wisely to save water. For instance, make sure your washing machine and dish washer completely loaded before you turn them on.
Do not neglect any leakage in your kitchen, bathroom or any other part of your house. Get it fixed immediately to avoid wastage of water.
Using less electricity is an indirect way to save water. This is because power plants use several gallons of water.

Conservation of water must taken seriously. The government of every country should restrict activities that result in water pollution and wastage of fresh water and the citizens must provide complete support in this direction. Each one of us should realize the importance of water and take it as our responsibility to use the simple ways mentioned above to conserve water.
