  • The Problems with Water Desalination

    1052 Words  | 3 Pages

    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.

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.
