除非你用 biodegradable 的垃圾袋否則用垃圾袋和買物塑料袋對landfill影響完全無分別 還能真正用少了

塑料袋子

每一年真正能回收再利用的百分比低得驚人

Those grocery-bag drop-off boxes, she says, are glorified trash bins. That swirly recycling symbol on coffee lids and granola pouches is more fantasy than fact. Clear plastic bottles are recyclable: green ones are not.  

In 2022, she estimates, the recycling industry has the capacity to process about 21 percent of the plastic used in water and soft drink bottles, 10 percent of milk jugs and juice bottles, less than 5 percent of grocery bags and shrink wrap, less than 2 percent of ice-cream tubs and coffee pods and less than 1 percent of plastic cutlery, coffee lids and DVD cases.  

最重要的是 Reduce, 減用,  Reuse 重用 比方 disposable 的東西用幾次後再 dispose 它。 Recycle 再利用。這個需要很高的成本 所以真正 Recycled 的比例是非常小。

三個 R 的排名是 Reduce, Reuse, Recycle.  前麵兩個對環境保護的 impact 高太多了。

至於用垃圾桶 liner 來批判主人家的人 隻能說太 low 了。去人家裏作客 鷹一樣的眼光來決定主人家肯不肯花錢 這該得多低的 self esteem 才能有這個心理？下麵守月說得一針見血．
