Water Pollution

The sea is full of bacteria, plants and animals which eat waste. The sea cleans itself if we do not use it as a dump. But if we dump too much waste in the sea, the bacteria, plants and animals cannot recycle it quickly, so the water becomes polluted. Chemicals from farms and factories get into the rivers; and the rivers carry the waste to the sea. The chemicals get into the food chain and so fish and other sea animals can become dangerous to eat.

The worst kind of sea pollution is oil pollution. Oil is black and dirty and there are toxic chemicals in it. If oil gets in the sea water, it stays on top of it. Air cannot get to the plants and animals under the water, and they die. Water birds become dirty with oil and are not able to fly. Very few of them survive. One of the worst oil pollutions in the world took place in 2011 in the Gulf of Mexico, when millions of tons of oil went into the sea. People had to work for months to stop the pollution and to clean up the place.

In the Gulf War in 1991 people themselves put oil on fire. A lot of oil went into the sea, got onto the ground. There were lakes of burning oil everywhere. The oil went down under the ground and polluted the water there. The pollution was terrible. Electric street lights burned all day in Kuwait because of the smoke from burning oil. Black and dirty rain fell on the Himalayan Mountains, thousands of kilometres away.
