1、使用一次性塑料袋的危害Againsttheuseofdisposableplasticbags塑料袋的確給我們生活帶來了方便，但是這一時的方便卻帶來長久的危害。Plasticbagsdogiveuslifetobringtheconvenience,butitaconvenientbutlastingharm.塑料袋回收價值較低，在使用過程中除了散落在城市街道、旅游區、水體中、公路和鐵路兩側造成視覺污染”污染外，它還存在著潛在的危害。塑料結構穩定，不易被天然微生物菌降解，在自然環境中長期不分離。這就意味著廢塑料垃圾如不加以回收，將在環境中變成污染物永久存在并不斷累積，會對環境造成極大危害。Lo

5、渣還會對食品的色、香、味造成直接影響。另外，一次性塑料袋還會釋放有毒氣體污染食品，長期食用一次性塑料袋包裝的食物易引發中毒。 據了解， 目前市面上用來包裝食品的塑料袋的制造材料， 一般都是聚乙烯和聚丙烯， 而一次性塑料袋大多是聚氯乙烯和聚苯乙烯制成的再生塑料制品， 對人體是有害的。其中有相當數量是利用垃圾站收購的廢舊塑料再生材料，且未經消毒，很可能含有大量病菌。Ontheonehand,theimpactonthehumanbody:forbreakfast,cookedfood,vegetables,fruits,snacksEveryday,whenweputallkindsoffoodi
