The Water Crisis and Solutions

World drinking water shortage If 70% of the earth's surface is covered with water, what is going on? Most of the earth 's water is not suitable for human consumption. The salt water is salt water, accounting for 97.5% of the total water on Earth. Freshwater is only 5% of the total water on Earth. Drinking water comes from fresh water. Fresh water is scarce, but rarer than people think: about 70% of freshwater is frozen on the ice sheets of Antarctica and Greenland, human beings can not.

Since 1981, we have worked on solving the water crisis. Several solutions may have changed over the years, but the fundamental problem is the fundamental problem that helps the community to clean up, sustainable water, safety, health and sanitation It will remain. We have solved this problem for 35 years and just started. 35 It is very similar to us ... There is no universal solution to the complexity of the water crisis. Rainwater storage tanks will function in rural areas of Nicaragua, but will not function in Indian big cities where space is limited. It is itself. As a result, sustainable water and sanitation for the next generation will be brought.

There are two solutions to solving the water crisis. First, you can learn how to convert salt water to fresh water. This is called desalination. Although this is currently possible, it is very expensive to implement and is difficult to implement on a large scale. The second solution is to improve the ability to turn dirty water into clean water. Scientists are currently using a variety of techniques to do this, and they think it is a way to help stop the water crisis from growth.

When I was introduced about water crisis and community-scale water intervention, it seemed to have a relatively simple and cheap but basic solution. A community-scale water supply point like a well can greatly solve many of the major problems faced by rural villages on the road to growth and development. This water sticking seems unquestionable and can not be ignored. I was drawn to exploring ways to achieve this important work with other people, I made up my mind.
