Last Sunday my father and I went fishing along a river. We found the water very dirty that we could hardly catch any fish in it. A lot of factories along the river always poured their waste water and rubbish straightly into the river, which made the river polluting. In this way most of the fish in the river was killed. Unless the rivers all over the country are polluted like this, no living things will be exist in the water. As we all know, environmental pollution do great harm to living things and human beings. Now more and more people have realized what serious this problem is. Our government is doing her best to take measure to fight against pollution. We expect that water in every river will be made cleaner and cleaner before long.
