The Limits to Growth (the linked text) led directly to the one-child policy in China and forced sterilization in India. Its supposedly scientific recommendations were adopted by the UN, the World Bank, western aid organizations, and the governments of those countries, with evil consequences.

Yes, this is a much better (for HN) comment. The one point I'd still make is that the word 'evil' in a comment like this is a bit of a jump to internet-drama and that detracts from the information you're providing. It's better to use more neutral language and let the reader draw their own conclusions. (I'm not saying evil doesn't exist—just making a point about internet thread dynamics.)
Linking the book The Limits to Growth and its message to the effects of the one-child policy is tenuous at best. The evolution of China in the 20th century is incredibly complex, and the effects of a single policy ocurring over decades cannot be directly caused by a single book.
