It’s just a fact - people are bad for biodiversity. I don’t think anyone can argue against it. What that implies is kind of dependent on your values, like you said, but it doesn’t mean we can’t discuss it and need to erase all such comments.
If all the humans that want the entire planet wiped of humans could start by setting the example with themselves, the rest of us will take it from here.
Seems to me like one should follow all the way through on those desires or else find some other ways of to live in which one could create value through their existence. To spout off that everyone should all die while not actually following through is one of the most selfish and destructive mind sets outside of murder and suicide.
Anyway, I have no doubts that life and people will be around for a very long time, it's our current lifestyles that are either going to voluntarily change or be changed for us.
So to offer a solution, I think we need to put a dollar value on biodiversity in addition to carbon tax so that these things start to show up on the spreadsheets of people with the actual power to change things.
They assume that they or their defendants will be one of the survivors so there’s nothing to worry about.
It’s the same issue with trying to prevent war when both sides think they can win. Sure there’s hardship but if you win didn’t you come out ahead? No one considers the trauma of the generation that has to actually do the fighting.
