“ Microbeads ”是塑膠微粒，它們常被加入各種產(chǎn)品中起打磨、摩擦的作用。比如，許多化妝品、護膚品和清潔用品中都常含有塑膠微粒。在英國，國會議員建議禁止這些微小塑料顆粒的使用，這是為什么呢？請聽 以下 的報道。
Tiny fragments of plastic pervade the seas from ocean depth to Arctic ice. They get eaten by small creatures and often clog their gut. Shreds of plastic can be found in oysters and mussels. The small creatures are prey for bigger animals, so the plastic travels up the food chain.
The fragments aren’t toxic themselves, but they attract toxins. The committee says more research is needed to see how much harm they are doing. But the MPs say banning microbeads in cosmetics would be a small but useful start.
