Rubbish are thrown into the oceans and sometimes, contaminants are also thrown into the ocean, these things that are thrown into the water pollute the water and cause diseases to be spread easily.Land pollution is caused by rubbish dumped into the land. Sometimes, the rubbish contain harmful substances that can harm the environment when it decompose. If it is burned, the air from the burning ofthe rubbish causes air pollution.Air pollution is also caused by the burning of trees. People in other countries practised a fst and easy way to clear the forest to grow their crops. This process is known as shifting cultivation. The people using this method rely on the rain to put out the fire. If the rain does not come, the forest will continue to burn continously and cause air pollution.Noise pollution is caused by loud noise,most likely happen when there is an aeroplane taking off or that is constrution happening.
