Sea Pollution
The pollution of the ocean is rapidly becoming a crucial problem on Earth. The major causes of sea pollution are oil spills, toxic waste, and dumping of other harmful materials into the ocean. This pollution will directly affect the living organisms in the ocean and indirectly affect human’s health and resources. We, as humans, should learn more about these in order to have the knowledge on how to solve this problem effectively.
Oil spill is perhaps the most publicly acknowledged cause of sea pollution. Large tanker accident like the Exxon Valdez had been rapidly known worldwide. This incident happened in Prince William Sound, Alaska in March 1989, where the Exxon Valdez, an oil tanker, grounded on Bligh Reef, spilling almost 11 million gallons of crude oil. It is considered as one of the most devastating human-caused environmental tragedy. Plenty of people didn’t realize that hundreds of millions of gallons of oil are quietly end up in our oceans by other sources such as routine shipping, run-offs, and dumping every year.
Toxic wastes are poisonous chemical and biological materials that are produced from industrial plants or facilities and agricultural work that are carried away through freshwater and into the rivers, lakes, and ocean. These dangerous pollutants include chemical contaminants such as Lead, Mercury, Asbestos, Sulphur, Nitrates, etc., and biological contaminants such as bacteria, viruses, protozoa, etc. Dumping of litter into the ocean can cause huge problems to the marine life. The ocean is a virtual dumping ground for rubbish. That garbage includes scrap fish nets, plastic bags, tin cans, glass or plastic bottles etc.
Sea pollution will cause different harmful effects on the wildlife. For example, oil spills frequently the kill marine lives and further cause extinctions. Blow holes of the whales and dolphins will be clogged by the oil, making them very difficult to breathe and communicate regularly. And the fur of the otters,
