Everyday on radio, on TV, and in the newspaper, we hear, see or read about many problems in the world, for example, pollution problems.

Air pollution is the first kind. It mostly comes from fumes released from motorbikes, cars, airplanes, 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.
