It is interesting!People in Africa cannot drink clean water; their children die because a the most part of our water has been polluted. Children in Kenya often have to go many kilometers to collect drinking water. Every 10 years about 46000 tons of radioactive wastes and about 3-8 million tons of oil are poured into oceans, seas and riversWater pollution kills fish and sea animals
DeforestationDeforestation is the destruction of forested lands. Forests are cut down for many reasons, but most of them are related to money or to people’s needs.
