When you think of the Arctic, you imagine an icy land of pure white snow. Others imagine it as the last really clean place left on Earth. We have polluted the deepest oceans with plastic trash, 1.

German scientists have recently found microplastics in Arctic snow. 2.Sadly, the scientists found 1,800 pieces of microplastic per liter of snow.

How is plastic pollution reaching the Arctic? According to scientists. "It's apparent that the majority of the microplastics in the snow comes from the air." They fall off plastic objects and are moved by the wind, just like dust. 3.Finding these plastics in Arctic snow means that we may breathe them in. An even higher amount of microplastic was found in the snow around cities.

The high concentrations found in snow samples suggest microplastics, which contain rubber or chemicals used in synthetic fabrics(混合纤维), may cause significant air pollution.

4.Scientists cannot answer this question for now, according to the world Health Organization. We do know that our bodies cannot take in "large" pieces of microplastics. However, if the plastics are small enough, they can find ways into our bodies and stay there for a long time. What's more, earlier studies have shown that microplastics may contribute to lung cancer risk, heightening the need to further assess the risks of taking them in, the study said.

Microplastics have also been found in rivers and oceans around the world. Previous research has found that they flow over long distances and into our oceans, damaging ecosystems along the way.5.The waste water then flows into rivers and out to sea, where they are eaten by sea animals. If people then eat these animals, it means that we're eating the plastic as well.

A.Are they bad for us?

B.and now it's the Arctic's turn.

C.so we should take action to protect the world.

D.They mix with ice in the air and fall to the ground as snow.

E.Microplastics are pieces of plastic smaller than 5 millimeters.

F.They start in our water when we wash clothes with plastic fibers.

G.Is plastic pollution doing great damage to our global economy?
