Think “Easter Island”....
The biggest mistake mankind has made in history is to violate the first law of nature. “Adapt to your environment.”
We learned to adapt the environment to us. Trees are cut to build a home. Minerals are taken out of ore to build the very phone I am typing on. Etc.
When we moved from nomadic lifestyles to settlements, food excess (agriculture) and safety (settlement) eventually led to over-population.
We are here. We are the top predator with no natural enemy other than ourselves.
We are so smart, ..., it has worked against us. Our excesses has the planet protesting. ....
