The ocean and we are a whole， first of all， the ocean itself has great handling of pollutants， dilution， diffusion， oxidation， reduction and degradation of purification But the capacity is not unlimited， when toxic and harmful substances accepted by the local waters more than its own self-purification ability， it will cause pollution of the In addition the ocean while contains many resources， but the regeneration of marine resources is the need of time， if the development of marine resources we uncontrolled and not pay attention to the protection of these resources， so there is always used in the light of So the protection of the marine is extremely
