Not to diminish any particular arguments, but this is how these conversations always play out in my view:

Stop burning fossil fuels.

But we are in overshoot.

Yes

But we won't be able to keep up agriculture.

Yes

But we won't be able to keep up industry

Yes

But we won't be able to keep up consumerism

Yes

But people will die.

Yes :(

But the rich will loses their riches

Yes

but but but

It doesn't matter what the cost is, that's the solution. The rest is simply consequence - and it grows greater by each day we ignore it.

Just because an ask is nigh impossible, does not mean that it is foolish or that it comes from ignorance.
