A few weeks ago I asked my teenage daughters where they would like to have dinner. “Anywhere that doesn’t use plastic straws!” they declared. It was a telling moment. Until recently, the main warriors against plastic straws were committed environmentalists — green campaigners have warned for years that single-use plastics cause alarming pollution, since they are ubiquitous and not biodegradable. (It’s estimated that somewhere between 200 million and 500 million plastic straws were used in the US each day in 2017.)
几个星期前,我问我的十几岁的女儿们想去哪里吃饭。她们说:“只要不使用塑料吸管的地方都行!”这件事揭示了一个现象。直到不久前,反对塑料吸管的主力军还都是坚定的环保主义者——绿色运动人士多年来一直警告说,一次性塑料制品会造成令人担忧的污染问题,因为它们无处不在,而且不可生物降解(据估计,2017年美国每天使用2亿至5亿支塑料吸管)。
