Water, water, everywhere, And all the boards grew smaller; Water, water, everywhere, not a drop to drink. A phrase taken from “The Rime of the Ancient Mariner” written by an English poet, Samuel Taylor Coleridge (Coleridge, 1798). The poem told the story of a ship that set sail and drifted towards Antarctica due to a storm. Luckily an albatross helps guide the ship out of Antarctica, but the sailor kills the albatross with his crossbow. The accident brought bad luck to the ship as the wind stopped blowing causing the ship to stall in the middle of the ocean. At this point the sailor leaves with the sentence that shows his frustration that although he is surrounded by water, he cannot drink the water to quench his thirst as it is salt water not suitable for drinking. This last poem tells that the ship's crew dies one after another leaving only the sailor who regrets his mistake and begins to appreciate marine life. The sailor then prays and the curse is lifted allowing the sailor to find his way back to shore (Shmoop Editorial Team, 2008). The earth is made up of 70% water and 97.5% non-consumable salt water. This leaves us with only 2.5% fresh water, and 70% of the fresh water comes in the form of polar ice caps in Antarctica and Iceland. Only less than 1% of fresh water is accessible, namely rivers, lakes, reservoirs and shallow groundwater, while the rest of fresh water consists of soil moisture and deep groundwater that is not accessible. Fortunately, the small source of fresh water we have is replenished by rainwater, thus reducing the possibility of water depletion (University of Michigan, 2006). While this is true for most of the world, we can't assume that rain is freshly reset... middle of paper... it's being done by Singapore with their NEWater project. NEWater is recycled wastewater that is treated using advanced technologies such as microfiltration, reverse osmosis in a semipermeable membrane, and UV disinfection that makes the final product safe to drink (PUB, 2013). Singapore also opened a seawater desalination plant in 2005 that hopes to explore the possibility of turning seawater into freshwater using biomimicry that mimics the biological processes of mangrove plants and euryhaline fish that extract l sea water using minimal energy compared to the current reverse osmosis technique which changes sea water into salt water is said to consume energy (Henley, 2013). We can also plan our water usage and use it efficiently at home to help sustain the globe's freshwater source so that the next generation does not have to suffer from water shortages.
