Plastic pollution is becoming one of the most serious threats to ecosystems. When you drive, the tires and brakes fly out of the little plastic. As more and more people enter the middle class and more vehicles are on the road, plastic pollution is likely to become more serious. According to a paper published in the journal Nature Communications, the researchers simulated how microplastics from cars move dating from densely populated areas into the environment.
Microplastics in cars have fallen from cities in Europe, Asia and the Americas to the Arctic, Greenland and oceans. The researchers found that the smallest particles that were easily blown away by phoenixes had an average life span of nearly one month. They calculate that 5.2 tons of small particles fall into the ocean each year and 20,000 tons into remote snow and ice zones. Small particles tend to fly to isolated areas, while larger particles usually fall nearby.
