How long does it take you to drink a bottle of water？ Maybe just five minutes. But the plastic bottle will stay in nature for 500 years！ Plastic does not disappear easily. It is a big problem for Earth.

For plastics， the trash can （垃圾桶） is not the last place they go in their lives. Every minute， a full truck of（一滿滿卡車的） plastic goes into the sea. They make the seawater dirty. They are dangerous for sea animals， too.

目前，全球還在以每年4億噸的速度生產(chǎn)塑料制品，而其中三分之一僅僅被使用一次。更可怕的是，全球每年所產(chǎn)生的超過3億噸的塑料垃圾，只有大約9%會被回收利用。所以，我們必須減少塑料污染?，F(xiàn)在，隨著人們環(huán)保意識的提高，越來越多的超市和商場開始使用玉米、木薯、甘蔗或者甜菜根等制成的可降解塑料袋替代傳統(tǒng)的塑料袋，以減少對環(huán)境的負面影響。
