Likewise, fears of over-population framed self-destructive policies, such as China’s one-child policy and forced sterilization in India. And, while pesticides and other pollutants were seen to kill off perhaps half of humanity, well-regulated pesticides cause about 20 deaths each year in the US, whereas they have significant upsides in creating cheaper and more plentiful food.
类似地，担心人口过度导致了自我毁灭的政策，比如中国的计划生育和印度的强制绝育。此外，尽管杀虫剂和其他污染物被认为会杀死一半人类，良好的杀虫剂管制让每年美国死亡人数只有20例，同时，杀虫剂的使用创造了更廉价、更充足的粮食供给。
