Read the passage and say what we do for keeping water clean.
|
Water covers over 75% of the Earth’s surface. It is very important for people and the environment. Only a small percentage of water is drinkable and fresh. The water in the sea and oceans is dangerous. Factories produce waste and pour it into rivers, lakes and seas. Water pollution affects drinking water, rivers, lakes and oceans all over the world. Polluted water kills sea animals. Fish die in polluted water. We must make filters to have clean water.
