>>510735604 (OP)>nature provides enough abundanceSadly this is as wrong as can be. Humans on planet earth are like the mold that colonizes a fallen apple.
96% of mammalian biomass is made up of humans and their livestock. Only 4% of mammalian biomass lives wild anymore.
There is around 8.000.000.000 humans. The next most populous primate counts 100.000.000, adjusted for mass only 10.000.
The human population can not be sustained without artificial fertilizers, usually derived from Haber-Bosch process or similar, with disastrous consequences.
The human population can not be sustained without agriculture, modern agriculture to be precise. This includes vast monocultures, pesticides, herbicides, entirely artificial crops and so on. All this destroys entire ecosystems and purges species.
Make no mistake: 'Nature' has very pittle to offer. The apple, cabbage, melon, banana, cereals, carrots and many more that you are used to are not natural. We consume only very few 'natural' things. For example nuts, meat of wild game and Fish.
Ehy is this? Because most peoples lizard brain will overpower their ragionality. When suffering causes humans to innovate and the innovation will lead to - at least short term - improved conditions humans will then figure they could just reproduce harder to the point where suffering is back up to where humans it is custom.
