One Cause

One of the important cause and most of the people do not about it and usually happen in the world is oil leaks from oil tankers. When there is oil leaks in the ocean it is very difficult to remove the oil. When the oil leaks, it is float over the water because it is less density than the water so the sun rays blocked. There are small plants live under the sea level. These plants needs these sun rays to grow so when these plants died the fish also will die because it will not find plants to eat.
