On the one hand, it takes about 200 years for a buried plastic bag to decompose and be absorbedby the soil. On the other hand, the use of disposable plastic bags will
indirectly do harm to people's health, which is less known to the public.

Therefore,they are eating the poisonous stuff while enjoying the tasty food.
一方面，只埋在地里的塑料袋需要两百年时间才能降解，被土壤吸收。另一方面，一次性塑料袋会间接对人体健康造成损害，大家对这一点知之甚少。有时人们为了省时省事，不用清洗餐具，就将买来的热腾腾的食物装进一次性塑料袋里。而他们并不知道袋中的化学物品在高温下会释放出来。因此，在享受美食时，他们吃的其实是有毒物品。
