The world uses about a thousand million tons of water a day. Water is a precious resource and everyone should have his or her right to use it. Yet more than 700 million people around the world have trouble getting clean water.
Treating waste water is a good way to provide fresh water for us. And it also helps to protect the environment by keeping
waste out of rivers and oceans. 80% of waste water around the world is not treated at all, and it is running into oceans. But now we have got the technology to treat and reuse the waste water.
While 71% of our planet is covered with water, only about 2% is fresh water—that comes from rivers, lakes, ice and snow. The rest, 98% of the water, is in seas and oceans. It is too
salty to drink. Then desalination comes in.The salt can be removed from sea water. More than 19,000 factories have been built around the world, mostly in coastal countries. They process (加工) more than 92 million tons of water every day. But the technology they use requires a lot of energy.
Scientists are working to create a less costly technology. They want to produce 20 times more clean water and make
sure everyone has enough water to use. But for now, the world still faces the problem that many people don’t have enough clean water to use.
