Pollution of the world ocean

The ocean has long served as a dumping ground for waste products. Today the effects of this long-term dumping are becoming increasingly obvious. The water in many areas is now too polluted for fish to survive. Oil spills from drilling rigs and ship collisions pollute the ocean. The dumping of industrial and other wastes far out at sea adds to the problem.

Pollution of the ocean concerns all nations. Some pollutants are easily broken down by natural means, and are harmless to the sea. Other pollutants, however, enter the ocean’s food chain, where they remain for years. In addition, ocean currents carry pollutants far from where they originally entered the water. For example, the pesticide DDT has never been used in Antarctica. Yet scientists have discovered its presence in the livers of penguins and seals living in Antarctic waters.
