Water pollution
Water pollution is one of the famous and one of the largest problems in our world. People in Africa cannot drink clean water; their children die because a big part of our water has been polluted. Children in Kenya often have to go many kilometers to collect drinking water. At all over 2 million people don't have clean water. And we do not know how it will be in future.
But the pollute water killed animals and plants too. There is no ocean or sea, which is not used as a dump. Many seas are used for dumping industrial and nuclear waste. This poisons and kills fish and sea animals. "Nuclear-poisoned" fish can be eaten by people.
Many rivers and lakes are poisoned too. Fish and reptiles cannot live in them. There is not enough oxygen in the water. In such places all the birds leave their habitats and many plants die. If people drink this water they can die too. It happens so because factories produce a lot of waste and pour it into rivers. So they poison water.
But we MUST keep our planet and water of our planet clean. If we want to live, we should guard our clean water and do not pollute them because we could live without food about a month but without water we could die in 4-5 days. Let's keep our water clean!
