In the Arctic, it is snowing with particles of plastic
We have repeatedly written about the fact that the plastic is a serious threat to life on Earth. So, more than half of the inhabitants of the sea and ocean depths, including plankton, feed microplastics. In the international press regularly reports on the animal, which found in the stomachs of kilograms of plastic. However, the problems do not end there. Scientists have discovered that the snow falls in the Arctic, along with particles of plastic. But how is this possible?
What happens to the Arctic?
Because of global warming, the Arctic is rapidly losing ice. But the Arctic accounts for about 10 percent of all reserves of ice on Earth. Despite the fact that the amount of ice is constantly changing depending on the time of year, the World Meteorological Organization has estimated that over the past 30 years, the Arctic Ocean has lost 95 percent of perennial ice.
It turns out that the area of the Arctic in just one in 2017 has lost about 260 thousand square kilometers of ice. Melting Arctic ice threatens life on the Red List of polar bears. Among other things, it affects the rise in sea level and has an impact on the climate of the entire planet.
A bit gloomy forecasts: We are all going to die from the ice? Antarctica is melting before our eyes
And if for a long time, scientists thought that the melting of ice - the only problem in the Arctic, it was found that plastic pollution of the planet and got to her.
As the plastic was in the snow?
The work of the German and Swiss scientists published in The Journal of Science Advances. Researchers were shocked by detecting the amount of microscopic plastic particles in the samples of Arctic snow. There were about 10,000 particles per liter. Write in our Telegram-chat, whether it's a lot on your mind. Until now it was believed that the Arctic is one of the few regions in the world, is not contaminated by plastic. Lead author Dr. Melanie Bergmann expects to find in a number of samples of plastic particles, but not in the amount of 10,000 particles per liter. According to Dr. Bergman, microplastics particles caught in the Arctic snow from the air.
What is microplastics?
microplastics assumed particle size of not more than 5 mm. Scientists have long known that the air is polluted planet microscopic plastic particles. However, as the particles contained in the air, hazardous to health and whether it is dangerous, scientists say they can not.
The Arctic snow samples some plastic particles were so small that scientists could not understand their origin. Researchers also took snow samples from Germany and Switzerland. It turned out that the city's snow contains a lot more plastic than the Arctic.
By the way, the sea ice also contains plastic and it is very bad. These and other news, please visit our channel on Yandex. Zen. Discuss whether there are any places in the world, untouched by plastic can in the comments.
