A couple of scientists in Michigan are making big strides in pee-cycling.
Yes, you heard it right. This is the process of pee-cycling, where human urine is used to fertilize plants.
In fact, researchers at the University of Michigan are experimenting with using human wee as a sort of liquid fertilizer to make plants grow faster and more robust. It has been studied that human urine has all kinds of nutrients to help plants grow in the right concentration. And wee is a renewable, earth-friendly source of fertilizer that is more sustainable than most chemical fertilizers.
日前，密歇根州的几位科学家尝试将人类的小便循环再利用，并且取得了一定的进展。
是的，你没有听错。这个试验就是研究如何进行尿液循环，也就是说，尝试重复利用人的尿液来给植物施肥。
经过研究，专家们发现如果用人尿作为液体肥料，可以使植物生长得更快更健壮。数据表明，人的尿液中有各种营养物质，而且浓度适中，可以促进植物生长。另外值得一提的是，尿液是一种可再生的肥料，对地球不会造成污染，比大多数化学肥料更具可持续性。
