trains, and poisonous gases emitted from factories. Also, waste is dumped anywhere, even in the city
where many people are living. 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
