World population and water
With more and more people in the world, more and more water is used. In fact, water use is growing more than twice as fast as the world’s population! As a result, getting good, clean water is becoming a problem in many places. A lot of water is polluted and in many areas people have to walk a long way to get clean water for daily use. More than 3.4 million people die each year from drinking and washing with polluted water. So let’s do everything we can to stop the pollution and save water.
