and what about the diseases…. ????

yeah…. getting off this planet and establishing colonies of “post-humans” (since anyone born off Earth will, after a few generations will look nothing like us) is probably the only way to ensure the long-term survival of our species…

That being said, I must add that fixing the inequality in resource distribution ( like the fact that the US throws away more food annually than is needed to feed the hungry on the entire plant) will go a long way in m, if not fixing, then delaying a lot of the effects of the upcoming changes
