Glad you already learned this is probably nonsense. The wrong reasoning is very similar to much thought about overpopulation. The amount of people that makes for a place to be overpopulated is a function of how societies work and the technologies they have at hand. One extra issue there is that improvements in technology usually lead to population growth, so much progress gets cancelled out.

That’s a short but touching poem.

IIRC, this actually happens. When the balance is disturbed, the mushrooms go wild and destroy young sapplings. Could be I recall incorrectly and it’s actually other species. I cannot recommend The Mother Tree enough, it goes into great detail of the history of research into this

And we are still increasing the rate at which we are making it worse…

It’s a laughing stock here in Belgium
