'Paper or plastic?' The eco-friendly answer is 'Neither – reusable': 這是去年 The San Francisco Chronicle 上的一個報導.
“”If you're comparing a paper bag made from virgin timber with a plastic bag made with natural gas, the paper bag causes more global warming pollution, more biodiversity impacts and more water impacts,” said Allen Hershkowitz, a senior scientist with NRDC who has worked on life cycle analyses for two decades. “If the paper bag is not recycled, it will generate greater carbon emissions during incineration than plastic would, or greater methane emissions if it is landfilled.””
不管是塑膠袋還是紙袋, 製造或回收重新的再造過程, 都會造成污染. 重點是重復的使用, 才是真正的環保.
