People can move around and live in temperatures from well below freezing to cookable desert heat.
Plants cannot. If a forest needs to migrate northward to follow changing climate, it's movement rate is measured in feet per year. Domesticated crops could be moved a bit faster with the aid of people, but there really aren't enough of us to get out there and save all the plant life that would be at risk, assuming we even had the foresight to try to do it. Again, this is only one of many variables, probably too many to count. But we have found previously that ecosystems are both hardier than we would expect in some respects and more fragile than we would expect in others.
