It looks like we introduced the invasive Asian ladybirds and ended-up killing off most of the native ladybirds. Now I have smelly orange beetles trying to get into my house. Thanks, other humans!
(It's times like these that I think the last human dying can't come quickly enough.)
That was October last year and they got into my car. Now in Sweden I saw some of them crawling out of the car last month when it got a bit warmer.
It's self-hating human comments like yours that beg for the obvious response: why not start with you. But I don't wish that on anyone. Hummankind are part of nature, not supernatural, so if you love nature you should love humankind, and ergo, yourself.
I don't particularly care about conservation. I find the hubris humankind has repeatedly demonstrated to be supremely odious, though. The repeatedly-demonstrated attitude of putting ourselves outside of nature, saying "Oh, but this time our actions won't have unintended consequences...", fills me with white-hot rage.
I recognize that hindsight makes bad decisions seem self-evidently bad. I can't help thinking that some historically bad decisions must have seemed bad at the time, too, yet we made them anyway.
Maybe our evolutionary progeny will be imbued with an intuition that speaks to the complex behavior that arises out of dynamical systems. Maybe they'll innately understand that they're inside the systems they want to influence, and not apart from them. Maybe they'll have sufficiently long lifetimes to skew their thinking away from short term gains. Maybe they won't exhibit the willful ignorance and motivated reasoning that we do. Maybe they'll just be less stupid.
Aside: Your retort of saying, effectively, "kill yourself" followed by "Yeah, but I don't really mean that" does seem a little gauche. I suppose, taken in kind with my flippant statement, it's not so out-of-place, but I do wish that the whole "kill yourself" meme hadn't ever made its way into Internet discourse.
