I think that’s the one yes. Decreased food yield from 2040 to 2099 onwards.
Also, even if I’m not into that, an old fart like Nostradamus or something like that (I don’t remember his name) wrote at the time that humanity will be greatly reduced around the first part of the 21th century. And now scientific studies more or less agree with that.
I have hope that humanity will change, I have zero hope that the ones who can do things (industries, huge corporations, rich peoples, politicians) will do something.
Apparently it’s better to die seated on unused billions rather than having a living world for your kids.
