collapse of the old society

How about no? A saved life is just as valuable whether there are 70 million dead or 7 billion. And even if it's just delaying the sterilization of the earth by a month that gives billions of people and quintillions of animals a bit more time.

Work-life balance is important and improves productivity, so you should be spending time with your loved ones regardless of how productive labor is. But giving up is just a waste.

If we go extinct, we had better make the last decades of humanity worth living.

If we thread the needle as a species, bottlenecking down to millions or thousands until we can weather the storm, we had better make sure that the culture that makes it through is not the capitalists that built the hardest bunkers or the fascists who massacred enough people until the survivors made it through with no skill of their own or even the liberals who adopted post-hoc constitutional principles that leave them unprepared for the next catastrophe.

And if billions survive, then every person counts. And that means every tonne of CO2 or microplastics, every species, every micrometer of ocean rise, every acre of robust circular agriculture.

There is no scenario in which we just get to lie down and take it.

I agree to an extent. I think governments or more accurately the civil servants in government are taking it seriously. I work with a local Doughnut Economics group and 2 years ago we couldn't even get the time of day, now the amount of calls and emails we have gotten from state, city & county officials is amazing. They want to take it seriously its just they don't know how. However in my experience I think they are starting to adequately freak out now, they are just keeping a straight face because "don't want the public to panic".
