Garbage in the ocean as a factor in climate change

Massive pollution of the world's oceans began from the time when people invented plastic (the second half of the 20th century) and began to actively introduce it into their life. Despite the usefulness of this type of product in industry and in everyday life, this "achievement of civilization" in natural conditions decomposes for more than a hundred years (and taking into account the HCC content, this period reaches millions of years). A single water basin is therefore one - the plastic thrown into any river or sea, thanks to ocean currents, gets lost in huge islands. In fact, plastic has become a victim of the scourge of punishing humanity's own success.

To date, a total of 8.3 billion tons of plastic have been produced worldwide. Of this, approximately 6.3 billion tons are now garbage, 79% of which is in landfills or in the environment. If at the end of the 20th century the content of garbage in the ocean was estimated at 400 g / km², then by 2015 it was already 1230 g / km², and in 2020 it exceeded 2000 g / km². The number of small particles is estimated at more than a trillion, and large ones account for 93% of the total mass. In total, this mass, toxic to the ocean, is at least 79 million tons. The size of the center of the largest garbage patch is estimated at one million km2, and the periphery extends to another 3.5 million km2.
