Dear listeners, today I want to telk about the pollution of the oceans in the world.
All serious cases of ocean pollution are related to oil, due to frequent accidents and poor maintenance of cargo ships.
Of course, a beautiful sight from afar, but ugly if you look closely at the consequences of oil spills in the ocean.
The land and the ocean are connected by rivers flowing into the seas and carrying various pollutants from the soil, such as : oil products, oil, fertilizers. All this ends up in the ocean and thus pollutes it. In small quantities, they enrich water and promote the growth of plants and fish, and in large quantities, they destroy ecosystems.
Accumulations of plastic waste form special garbage spots in the oceans under the influence of currents. At the moment, five large accumulations of garbage patches are known - two each in the Pacific and Atlantic oceans, and one in the Indian Ocean. These waste cycles are mainly made up of plastic waste from discharges from the densely populated coastal areas of the continents.

Around Europe and off the eastern shores of North America, sandbanks are being set up to breed oysters, mussels and fish vulnerable to toxic bacteria, algae and pollutants. ( Animals should use garbage when building houses, as they do not distinguish it from other natural materials. Interesting alternative, of course, but not all trash is safe, some may be toxic or could injure the animal. )
But if you are a person who doesn't care about nature outside your home, then I hasten to upset you, water pollution is also dangerous for people. The harmful organisms contained in wastewater breed in molluscs and cause numerous diseases in humans. The most common bacterium, E. Coli ( кишечная палочка ), is an indicator of infection. Chemicals from the soil entering the sea penetrate the tissues of living organisms. Such "contaminated" fish can be eaten by humans. Thanks for attention.
