Loss of keystone species[1]. Say, if bees went extinct, our agriculture would come crashing. We still rely on other organisms for a lot of important, sometimes poorly understood until too late[2] functions that sustain our civilization.
If bees went extinct, it would affect none of the essential crops we grow. Grains are wind pollinated, not insect pollinated.
More generally, I'm sure extinctions would wreak havoc on wild ecosystems. But we grow food by explicitly destroying wild ecosystems, replacing them with monocultures. Crops seem to grow just fine anyway.
I think it's a bit telling/alarming that you seem to be "okay" with monocultures and mass extinctions because we don't seem to be affected (at the moment).
This discussion is about the claim it causes civilization to collapse, not whether I'm okay with it. But hey, thanks for steering this in an ad hominem direction.
Which you steered there because you wanted to be nitpicky about the biodiversity issue, where what I originally said was that civilization is likely to collapse because we can't seem to address the climate, biodiversity and energy problems.
But hey, thanks for steering it in an ad hominem direction.
I'm not allowed to question a statement that loss of biodiversity could cause civilization to collapse in the next few decades? Really?
This is an objective statement about facts out in the world, and as such it is completely acceptable to ask how this position was reached. I questioned it because it looked like bullshit to me. You don't think bullshit should be called out?
