The biggest brain fart of humanity is our tendency towards monoculture (for scale). Nature is very obviously showing us how to sustain an ecosystem and yet in our incredible hubris we’re like “nah, we got this”. We just want to swim upstream for the hell of it.
Nature doesn't try and do anything. Nature is constantly trying to murder everything around it. The most lethal diseases to man are natural, and often common skin bacteria which everyone carries.
There's a viral form of cancer which is wiping out the Tasmanian Devil right now, just because.
Nature and evolution has no plan and no morality, it has survivors and a balanced ecosystem is a cold war stalemate.
Nature is teaching us how to survive by trying to constantly murder us and everything else if you prefer. So we can gain knowledge by seeing what works for other surviving species around us.
I think one of our greatest flaws (and possibly main reason we are here today) is that we’re so self-centered.
Why do we monoculture if it will kill us long-term? Because it benefits us short-term. (And hey, maybe that gives us runway to solve the long-term problem).
But points to us for a world record pace speedrun on the downturn side of it. It’ll eventually bloom again once we’re done here.
