Not always does good news come alone.While NASA has reportedly found the evidence that liquid water did once exit on Mars,the water issue on another planet,the earth , should not be neglected.It is widely noted that the water resource on our home planet is becoming increasingly scarce in recent years, and, diverse contributing factors can be identified behind it.In the following,I shall explore the possible reasons for it and present my personal suggestions to water shortage.
The most obvious reason is the growing trend of overpopulation in major cities around the world. With their population skyrocketing to an unprecedented level of over 1- million in some giant cities such Tokyo, Shanghai, and Mexico City, the urban infrastructure is often hard-pressed to cope with the problem of providing clean water to city dwellers.
Moreover, in an attempt to provide adequate food supplies to their huge populations, many developing countries are undergoing a large-scale agricultural expansion that requires significantly more water resources for irrigation and livestock farming than before. Also, water as an essential component of their production is increasingly demanded by
various industries, such as fabric, chemistry and manufacturing.
Other reasons that result in a global dearth of water supplies include
rampant deforestation, encroaching desertification and contamination
of rivers, lakes and underground water.
Faced with this daunting challenge, the first priority is for governments to adjust their economic policies, promote sustainable development and stop damaging the natural environment. Besides, Third World countries need to launch nationwide campaigns to advocate the benefits of birth control and educate citizens on the use of contraceptive devices.
Also, the public’s ecological awareness should be raised to a higher level where people of all ages can understand the utmost importance of preserving natural resources and switch accordingly to more environmentally friendly ways of life.
In addition, every family can be encouraged to reuse water within the household. For example, in most Asian societies where rice is the staple food, the water used after cleaning rice contains various nutrients for plant growth and is an excellent detergent to flush the toilet.
Furthermore, the intriguing idea of converting the inexhaustible sea water to fresh water supplies will be the ultimate solution.
