Solutions To Sustain Freshwater Essay

1889 words - 8 pages

Would it be possible for humans to live without water? The answer is no because fifty percent of water is inside human bodies. In other words, water supports human lives, so every person is supposed to drink at least two litres of water everyday because it predominantly prevents them from being dehydrated. In terms of being the priceless resource, water is used in many fields such as agriculture, industry, business and so on. All preliminary products are comprised of water. Due to the abundance of water, most people seem not to be concerned about the way they consume this crucial resource. For example, in some countries, there are no dirty water treatment systems practising, and everyone can use water as much as they can as the price of water is cheap, too. However, in some countries, they lack water to access regularly and need to do trade with others in exchange for water. Also, Rogers (2008) notes, “that the problem is well-known makes it no less disturbing: today one out of six people, more than a billion, suffer inadequate access to safe freshwater” (As in New Delhi, para.3). There is no limit of the use of freshwater between one country to another, and it depends on the place people live. Even though there is a lot of freshwater available on the earth, we, people, should be worried about the proper water consumption. In order to thwart the water crisis from occurring one day, we should reverse our trend of using water by desalinating seawater, recycling waste water and reducing the unnecessary demand of water.
The first solution to deal with the problem of water scarcity is to desalinate seawater. Getting freshwater from the sea is taken into account because seawater is much more than freshwater in reality. As Villiers (1999) states, “after all, 97 percent of the water on earth is seawater, and other 3.5 percent of the dissolved solids that make it unusable for humans” (p.133). It is precisely true on the account of the fact that people have not taken any advantages of seawater so far except fishing. Probably 96.5 percent of all the water around the globe is in the form of seawater which is too saline to be consumed directly (Thompson, 1999). Seawater desalination is a good deal in response to making seawater to become freshwater. It is the process of removal salt and other minerals from water. Mostly, in countries which do not have freshwater sources such as lakes or rivers, they start to adopt this method to increase their water supplies. Particularly, in Middle East, people who is getting richer and richer from selling their oil products, have the ability to build desalination plants. As Villiers (1999) continues, “there are already more than 7,500 desalination plants in operation worldwide, some of them tiny (and not counting the Keefer-inspired devices now installed on US Navy life rafts). The world's largest plant in Saudi Arabia produces 485 million litres a day of desalted water; the Saudi and other oil-rich countries are using...
