That's been the human situation for all of history. Psychologically we are terribly conservative and fragile but physically, we're the ultimate product of billions of years of evolution, having survived much bigger environmental changes in the meantime than we see today. We may not like it when we have to, but we are by far the best in the known universe at adapting to and changing our environment. Unfortunately, it remains to be seen how many of us will survive this process of adaptation.
