According to French media reports on the 10th local time, a new study showed that by 2019, there were about 170 trillion plastic particles in the world's oceans due to the impact of plastic waste pollution. Marine plastic pollution is becoming increasingly serious.
On March 8 local time, a study published in the international journal Public Library of Science showed that by 2019, the number of plastic particles floating in the world's oceans reached 170 trillion, with a total weight of about 2.3 million tons. It is noteworthy that the researchers analyzed the pollution of the Atlantic, Pacific, Indian Ocean and Mediterranean during the 40 years from 1979 to 2019, and found that there was no obvious growth trend of plastic waste before 1990. It fluctuated from 1990 to 2005, and began to surge after 2005.
Research shows that most of the marine plastic wastes are fishing nets and floating gear, followed by clothes, car tires and disposable plastic products. According to the study, these plastics will break down into smaller plastic particles after flowing into the sea, and some marine organisms will mistake them for food and swallow them, resulting in death.
In addition, according to the report jointly released by the Economist Think Tank and the Japanese non-profit organization "Nippon Consortium", from the current trend, by 2050, the annual use of plastic in the G20 countries will be twice that in 2019, reaching 451 million tons. According to the report, if no measures are taken to control it, the global plastic waste will further increase and aggravate marine pollution.
