The world will be fine. Its human society or specifically the working class who are fucked. Mostly by food scarcity due to drought and/or climate collapse.

We are already in the age of mass die offs, and low level extinctions, by the early 2030s mass extinctions will be the norm and by 2050naround 50% of all crops globally will fail on average. And that's only if thing stay the same trajectory as they are now. Major events like the gulf stream collapsing could make things much worse much quicker.

So I think I will just spend my money enjoying life while I can, before the global famines happen :)
