Water is essential for any living thing on the Earth: plants need water to grow; human can’t live without water for 3-5 days. However, the world is facing a serious issue knows as water scarcity – this is major caused by the increment of human activity and climate change. There are two possible solutions such as implementing high technology to produce safe water and education for both children and adults. The increment of human activity is one of the major causes of water scarcity. As world population keeps growing, the need of clean also increases simultaneously. This means an additional amount of water from various sources, such as river, dams, and reservoirs … will be rapidly exploited for both daily general use and foods/goods production. As a result, the environment absorbs more polluted water, causing disease and death. Furthermore, climate change is also a key factor causing the rareness of water. Because of human activities, the environment has been significantly polluted: deforestation allow rain water to go directly into ocean without human utilization. Furthermore, droughts reduce the amount of water going into dams and reservoirs. Higher temperature also results higher melting speed of glaciers, not only wasting a huge water resource but also raising sea level, causing floods. Fortunately, there are two available methods to save more clean water. First, high technology is speedy changing and improving, it can be used to generate more safety water. As tradition approaches such as building dams and reservoirs are due to its high cost and lack of sites. On the other hand, sea water is close to be an unlimited water resource. Though desalination is an expensive technology, it can be a brighter future of humanity. Also, used toilet water can be recycled and use for agriculture or heavy industry. Second, apart from technology, education will contribute in saving water mission. During early age, children will be taught how to use water efficiently, either in...
