Oceans are the largest ponds on the planet. It would seem that garbage, domestic water runoff, acid rain should not significantly worsen the state of ocean waters, but this is not so. Intensive anthropogenic activity affects the state of the World Ocean as a whole.

plastic trash

For people, plastic is one of the best inventions, but for nature, this material has a detrimental effect because it has a low level of biodegradation. Once in the ocean, plastic products accumulate and litter the waters, their number increases every year. Phenomena such as garbage patches form on the surface of the water, where there is more plastic than plankton. In addition, the inhabitants of the oceans perceive plastic as food, eat it and die.

Oil spill

Oil spills are a devastating problem for the oceans. It could be an oil spill or a tanker wreck. About 10% of the total amount of oil produced annually leaks. A huge amount of money is required to eliminate the disaster. Oil spill cleanup not doing well enough. As a result, the water surface is covered with an oil film that does not allow oxygen to pass through. In this place, all oceanic flora and fauna die. For example, the consequence of the oil spill in 2010 was the change and slowdown of the Gulf Stream, and if it disappears, the climate of the planet, especially North America and Europe, will change significantly.

Fish catch

Fishing is a pressing problem in the oceans. This is facilitated not by ordinary fishing for food, but by catching fish on an industrial scale. Fishing boats catch not only fish, but also dolphins, sharks, whales. This contributes to the active reduction of the populations of many inhabitants of the ocean. The sale of fish products leads to the fact that people deprive themselves of the opportunity to continue to eat fish and seafood.

Metals and chemicals

There are many sources of water pollution in the Atlantic, Indian, Pacific, and Arctic oceans. Ocean waters contain the largest amount of the following chemical compounds and heavy metals:

  • chlorides;
  • sodium polyphosphate;
  • sulfates;
  • bleaches;
  • nitrates;
  • soda;
  • biological bacteria;
  • flavors;
  • radioactive substances.
  • This is not a complete list of the dangers that threaten the oceans. It should be noted that each person can take care of the oceans. To do this, you can save water at home, do not throw garbage into water bodies, reduce the use of chemicals.
