Water, water, every where, And all the boards did shrink; Water, water, every where, Nor any drop to drink. A phrase from “The Rime of the Ancient Mariner” written by an English poet, Samuel Taylor Coleridge (Coleridge, 1798). The poem told a story of a ship which set sail and adrift to Antarctica by a storm. Luckily an albatross help guide the ship out of Antarctica but the mariner shot the albatross dead with his crossbow. The incident brought bad luck to the ship as the wind stop blowing causing their ship to halt in the middle of the ocean. At this stage where the mariner came out with the phrase which shows his frustration that although he is surrounded by water, he cannot drink the water to clench his thirst since they are salt water which is unsuitable for drinking. The poem latter narrate about the ship crew dies one by one leaving only the mariner as he latter regrets his mistake and start to appreciate marine life. The mariner then prays and the curse lifted allowing the mariner to find his way back to shore (Shmoop Editorial Team, 2008).
The earth is made up of 70% water and 97.5% of it is salt water which is not consumable. That leaves us with only 2.5% of fresh water and 70% of the fresh water comes in the form of icecaps in Antarctica and Iceland. Only less than 1% of the fresh water is accessible which were river, lakes, reservoirs and shallow underground water with the rest of the fresh water are soil moisture and deep underground water that is not accessible. Luckily, the little source of fresh water that we have is being replenished by rain water thus reducing the chance of water exhaustion (University of Michigan, 2006). Although this is true for most part of the world, we cannot assume that rain replenish fresh...

...s is done by Singapore with their NEWater project. NEWater is recycled sewage water which is treated using advance technology like Microfiltration, Reverse Osmosis in a semi-permeable membrane and UV disinfection which makes the final product safe for drinking (PUB, 2013). Singapore also opened a Seawater Desalination plant in 2005 which hopes to explore the possibility of turning seawater into freshwater by biomimicry which is mimicking the biological processes of mangrove plants and euryhaline fish extract seawater using minimal energy since the current Reverse Osmosis technique of changing sea water to salt water is said to be energy consuming (Henley, 2013). We also can plan the water usage and use the water efficiently at home to contribute in sustaining the freshwater source of the globe so that the next generation will not have to suffer from water shortage.
Desalination plants overall could be a huge benefit to society for its high quality of water and intuitive water treatment techniques, however the big environmental impacts and high costs to produce water at a desalination plant makes it unfavorable to most communities especially the poorer communities. Although costs for the production and upkeep for a desalination plant has been going down while the technology of it rises, the only true benefit for having a desalination plant would only come into affect when it is near a body of ocean, such as Tampa Bay Water. All in all desalination plants could soon be the face of future water treatment plants and water sources, but for the present time it is still only a niche water source.
Presently, in the USA the California state is starting suffer with water crises. Therefore, the state started planning many desalination plants. There are three current desalination station, and the government is planning more fifteen. Figure 9 shows the desalinations plants in the California state. There are many critics about the desalinization plants.20 Arguments use against the plants are which use huge amounts of energy, and is very danger for the marine life.20 Desalinated water construction costs approximately $2,000 an acre foot.20 In addition, to produce one gallon of drinking water need two gallons of seawater.20 This process consumes about 38 megawatts to remove 100 million gallons of seawater per day.20
Perth has two seawater desalination plants, one is completed in 2006 with a 123,000 m3/d (45 GL/yr) water production powered by a wind farm. The other one is almost double size of first one, which is 100 GL/yr powered by 65 MWe of dedicated renewable energy, which together provide half the city’s needs.

Water is the most vital thing for all life, yet it is a limited resource. Only 2.5% of water on earth is freshwater, and even that amount is being diminished by pollutants.

Renee Cho of state of the planet Blog, a blogs from the Earth Institute says in the opening of his article entitled From Wastewater to Drinking Water, that “Across the globe, 2 out of 10 people do not have access to safe drinking water.” To bring it closer to home, right here, in the U.S, many states and cities are suffering from water shortages and droughts. Robert Glennon in his book Unquenchable: America’s Water Crisis and What to Do About It reports “Americans use 24 gallons of water each day to flush their toilets—approximately 5.8 billion gallons.” Most of this wastewater will not be reused for drinking but instead cleaned to EPA standards of Drinking and then used for other reasons. Cho reports that most of the wastewater is released into rivers and lakes, and some is reused and recycled for” irrigation, landscaping, industry and toilet flushing.” While it may be good to replenish sensitive ecosystems that sustain wildlife, fish and plants who are left vulnerable after water is diverted for the needs of urban and rural communities. It is also important to limit the amount we take from these sources in the first...
It is the duty of the sea to act as a navigation system, so humanity is always going in the right direction. It also acts as a way for us to get the water we need to survive, to catch the food man needs for nourishment, and provide cleanliness, which is equal to godliness. This stanza portrays water as a friend, that guides us in the right direction, and a parent that provides us with everything needed to survive and be prosperous. This once again strikes home the point that the world is an extension of God, created to bring mankind ultimate pleasure - the water that He created acts as a willing servant, and parental figure, such as God is usually
The average human can not live any longer than three days without water. Many of the world’s fresh water sources are running dry or are being contaminated, particularly in developing nations, leaving many without safe water to drink. Only two and a half percent of the Earth’s water is freshwater, and less than one percent is accessible by humans (not tied up in ice caps). This one percent of the Earth’s water supply is expected to sustain a population of over 7 billion people, each needing 2.6 liters a day to remain fully healthy, plus all of the water required for agriculture and industry. These scenarios will only become more and more prevalent as time moves on and we consume more water. The United Nations has classified our planet as being in the midst of a global “water crisis.” Global water supply and shortages are becoming an incredibly real and serious issue, and planning for the future is key to preventing population decline due to a lack of safe drinking water. Shortages of drinking water lead to wars and serious international conflict for basic human survival needs. One of the most popularly and commonly proposed solutions to this problem is to create seawater desalination plants to remove salt from ocean water to make it safe to drink. These water desalination plants, however, are not a viable option to carry us in to the future due to their potentially harmful impacts and expenses.
Freshwater is quite scarce, but it is even scarcer than one might think: about seventy percent of all freshwater is frozen in the icecaps of Antarctica and Greenland and is unavailable to humans. Most of the remainder is present as soil moisture or lies in deep underground aquifers as groundwater. It is not economically feasible to extract this waster for use as drinking water. This leaves less than one percent of the world’s fresh water that is available to humans. It includes the water found in lakes, reservoirs, groundwater that is shallow enough to be tapped at an affordable cost. These freshwater sources are the only sources that are frequently replenished by rain and snowfall, and therefore are renewable. At the current rates of consumption, however, this supply of fresh water will not last. Pollution and contamination of freshwater sources exacerbate the problem, further reducing the amount of freshwater available for human consumption. Something must be done if humans want to even survive in the near future: the lack of clean drinking water is already the number one cause of disease in the world today. The first step is worldwide awareness of the water crisis: governments and the citizens they govern worldwide need to know about this problem and be actively involved in solving this problem.
Water is on of the most precious natural resources that exist on our planet. “It is delivered from the atmosphere in the form of rain, snow, hail, fog, and condensation and returns to the atmosphere by evaporation and transpiration” (Hannigan 1969). Although many of us love activities that have to do with water, we disregard it and pollute out rivers, lakes and oceans. Slowly but surely we are going to harm out planet till no return. Protecting and conserving nature will secure a better future. 71% of earth is covered with oceans. Sounds like a lot right? Imagine ...
Water pollution has affected many people and animals. Water pollution is the disposal of garbage into a water stream. Some of the water pollution is from littering, some water pollution is done by chemical leaks, and others by ships. Also, There is much information about water pollution.
Freshwater in the world makes up only a small portion of the water on the planet. While the percentage of water in the world is nearly 70%, only 2.5% is consumable. Even further, only 1% is easily accessible to basic human needs. According to National Geographic, “by 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with two-thirds of the world's population living in water-stressed regions as a result of use, growth, and climate change.” With this current trend, water will become more immersed in environmental, economic, political, and social changes.
Water is an essential nutrient that our body requires every day. Without water human life cannot be sustained. Water deprivation kills faster than lack of any other nutrient. People do not think of water as a nutrient and don’t realize the important role of water in the body functions.
“Water is the lifeblood of this planet. Every time a good is bought or sold there is a virtual exchange of water. Every time we interact with water, we change it, redirect it, or otherwise alter its state. We have never learned how to efficiently manage water.”(Cluckie, 2009) Ian Cluckie, Professor of Hydrology and Water Management, emphasizes the fact that humans can’t survive without water. Although water is a renewable resource that can replenish under hydrological cycles, our intervention has interrupted its natural cycle causing its supply to decrease.(Cluckie, 2009)
