thirsty, you will buy
quench thirst? I believe most people's answer is: yes. But did you know that if you regularly use
to drink water, you may consume up to 90,000 "microplastic particles" a year.
, "microplastic particles" are widely found in our food, water and even in the air, according to a new study published in environmental science and technology, an authoritative international journal. Americans consume between 74,000 and 121,000 "microplastic particles" per year.
, the dangers of these invisible "microplastic particles" to humans are not yet known. But the researchers say some of the "microplastic particles" are small enough to enter human organs and trigger an immune response.
of "microplastic particles" that take more than 400 years
the ubiquitous partial degradation of single-use plastics comes from plastic products. The United Nations Environment Programme says plastic waste pollution is one of the world's leading environmental problems, generating about 300 million tons of plastic waste each year. On The 10th of this month, the Canadian government announced that it would ban the use of a variety of disposable plastic products, including disposable tableware, straws, etc., from 2021.
plastics are made from hydrocarbons from natural gas, oil and coal and are polymers. Most of the plastics commonly found on the market are hydrocarbons. Plastics are widely used because they are light and robust, easy to process and inexpensive.
1950, global plastic production was about 2 million tons per year, increasing to about 400 million tons in 2018. Most of these are "disposable plastics", including plastic bottles, plastic cups, plastic cutlery, plastic bags, and even cigarette filters.
millions of tons of plastic waste are dumped into the sea or placed in landfills every year. A plastic bottle takes more than 400 years to degrade, and less than a fifth of the world's plastic supplies are recycled.
according to data published by the United Nations Environment Programme, if humans continue to use disposable plastic products unbridled. By 2050, the global plastic waste could reach 12 billion tons.
plastic waste is a global environmental problem that needs to be solved urgently. At present, more than 60 countries and organizations have begun to restrict and ban the use of single-use plastic products. But even so, it is estimated that between 1 and 5 trillion plastic bags will be produced globally each year, an average of 600 million per hour. If you tie the plastic bags produced each year together, you can circle the earth 7 times.
Million tons of plastic waste into the sea every year Marine life suffers
we mentioned earlier, millions of tons of plastic waste are dumped into the sea every year and cannot be degraded for a long time. This has affected animals in the oceans, with five species of marine life currently most affected by plastic waste pollution.
the first, turtle. In 2018, scientists examined more than 100 turtles and found plastic contaminants in each turtle.
the second, fish. Scientists say more than 50 species of fish have miseeduled plastic waste.
the third, seal. Scientists often see seals in garbage such as plastic bags.
fourth species, seabirds. Every year, plastic pollution kills about 1 million seabirds.
the last one, whale. Whales are known to eat plastic waste by mistake, with more than 40 kilograms of plastic waste found in a whale's stomach.
, plastic waste pollution affects 800 species of marine life, these five are just some of them.
three-quarters of all marine waste is plastic waste. Affected by plastic waste pollution, a large number of marine life dies every year. If humanity does not take it for granted, the consequences for the future will be unimaginable.
