Jordan Peterson explains why there is no problem with overpopulation. The human population will peak, technological increases will allow people to do more with fewer resources, and an increase in the wealth and standard of living of the poorest of the poor will lead to less destruction of the environment.
As I've mentioned earlier, and Jordan Peterson mentions in the video, humans are the only creature on the planet that has ever developed the concept of an ecosystem, and that's a relatively recent development. It hasn't been that long that humans decided the environment existed and needed to be protected, and we've made a lot of progress in that regard in a very short amount of time. Just ending open-air nuclear tests has dramatically reduced the amount of pollution that's being created. When you add to that other technologies, you get to a point where you have a well-developed country like the United States, which is a carbon sink (meaning the United States sequesters more CO2 than it emits, unlike places like China and India, which have no environmental restrictions and produce pollution so thick that it causes accidents.)
The major problem Jordan Peterson mentions regarding human misuse of the environment is overfishing and polluting the oceans (I would add depletion of groundwater). This is a serious problem, but not an insurmountable one, and if we let technology develop without the misanthropic mindset of the global warmingists controlling government policy and interfering with human advancement, then we should be able to find a solution before these problems become unsolvable.
