Paul R. Ehrlich's The Population Bomb and the mindset behind it is something I deeply despise.
I vividly remember that a childhood friend of mine explained to me that wars aren't that bad after all, because overpopulation is a serious problem. That's what a seven year old takes with him, when his parents frame babies born somewhere in the world as something bad.
And despite Ehrlich's predictions - or those of the Club of Rome with The Limits to Growth - never being near the truth, the thinking that humanity is somehow a burden to reality is widely spread.
It leads to all kinds of decel & degrowth decisions: no bold approach to solve housing, having no kids, a guilt-based approach to politics, or putting the foot on the brake on scientific achievements.
I'll give you an example: when my peers graduated, some idealistic ones went to Kenya to help out in schools. That's very logical to me - you have it good, you want to help others to get better as well.
The guilt-based approach: as we caused the trouble on the earth, we will tear down BASF, make ourselves worse off so the inequality goes down. We will then observe the poor as Noble Savage and don't want to intervene with "nature's way".
The outcomes are very, very different.
The economic and scientific achievements of the 20th century have been a miracle for humanity. We shall never give in to those that see humans existing as a burden. It is literally insane and shall never lead decisions, especially those for others.
I'm very bullish on humanity.
