“ Microbeads ”是塑胶微粒，它们常被加入各种产品中起打磨、摩擦的作用。比如，许多化妆品、护肤品和清洁用品中都常含有塑胶微粒。在英国，国会议员建议禁止这些微小塑料颗粒的使用，这是为什么呢？请听 以下 的报道。

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.
