The second pollution problem is sea pollution. Many people earn their living from fishing in the sea, and the fish they catch feed many people. But the sea has become so polluted from oil spills and factory wastes that the fish are dying. This pollution is not only killing the fish, but also affecting those people who eat fish.
Seldom do you find a place nowadays that is not polluted. This problem is growing more difficult every day. We must find a good solution that makes the world a better place to live.
