Everybody knows what needs to be done. Parenthood needs to be sustainable for the parents. There’s just no political will to implement a policy that will only start paying off in 20+ years. Every politician kicks the can down the road, or implements half-hearted policies.

We can predict a disaster 2 centuries in advance, and yet accelerate the onset of the disaster until it’s almost too late to avert it. What makes you think humanity would do anything useful if they had a thousand years? We’d just revert to our old behaviour because the urgency wasn’t there any more.
I think we might just have a better shot, or at least more time to adapt to a harsher climate. I’m not saying this is a guaranteed solution
