把这一句，留给此刻的你

Buying phosphate-free soap allows you to say, 'My detergent doesn't have the harsh chemicals others do.' The question is, how are you washing with it? The very worst thing for the Earth about detergent is that we heat water to use it.

购买不含磷酸盐的肥皂可以让你说，“我的洗涤剂不含其他人使用的刺激性化学物质。”“问题是，你是怎么用它洗衣服的?”对地球来说，洗涤剂最糟糕的地方是我们加热水来使用它。
