Speaking of pollutions, most people may think of air pollution and water pollution, which are highly relevant to our everyday lives. However, to the surprises of most of us, ocean pollution may be the most difficult one to solve of all.
Unlike other pollutions, ocean pollution stems from numerous sources. Industrial and domestic sewage which flows into oceans, oil leaked from ships and oil drillers, and acid rain fall into the seas are just a few of the causes. Because of the diversity of the pollutants, including heavy metal, acid, base, organic substance and waste heat, the plight is more complicated and grave than other types of pollutions.
Besides, the toxic chemicals in oceans will accumulate in bodies of marine life, which turns out to damage our own health when we eat those polluted fish. What is worse, once the pollutants are mixed into the oceans, it takes centuries to curb the toxicity to a safe standard. Thus, once we found factories that produce toxic sewage, we’d better realize that one day we will burden enormous costs.
In addition, the pollution is without borders. When pollutions occur, there is little can we do to stop it from spreading. Therefore, ocean pollutions usually results to unpredictable harms to the planet. For example, a single leaked oil ship or off-shore driller may suffocate thousands of sea birds and several schools of marine habitats. In some devastating cases, the leaked oil easily spoiled hundreds of square kilometers of coral reefs. Moreover, if we go on ignoring the seriousness of ocean pollution, several vulnerable species will undoubtedly go extinction.
Ocean pollution is destructive in biodiversity, environmental sustainability, and our way of lives. It is the business of everyone, and we are the solution.
How can we defend our oceans? We can reject the development of the industries which have the potentials to aggravate the catastrophe. We should insist the sustainable green energy be pursued instead of fossil fuel, and support adequate protective criteria be made. Besides, we should urge the official to supervise the waste and rubbish disposal. Meanwhile, we should try our best to solve other pollutions simultaneously, for they are closely co-related. Also, we should advocate the urgency of ocean protection.
