For a long time, water on Earth was threatened by pollution, and governments did little to stop it. Today, we know that pollution is very harmful to our planet. For this reason, governments have decided to pass laws to stop pollution. Not all pollution has been stopped, but the picture has gotten better over the last thirty years. Governments are usually there to listen to the needs of the people, and one of humanity's basic needs is clean water.
Laws help make clean water possible.
For example, laws may say that an industry must not allow certain chemicals to enter the water near their factories. Laws may also tell communities how clean water must be before it is pumped into homes. All rights reserved. Planet Zoom is not affiliated with WGBH Educational Foundation.
