Earlier quoted context omitted.
I think that if everyone gave up air travel, individual automobile transport, and meat and dairy and lived in a max 110m2 apartment you could say that. But it seems that there are a lot of people who simply don't care.
I would rather humanity have a bloody war that wipes out 90% of us than live the miserable life you have described. My life does not fit within walking distance of a 110m2 box.
(As an aside, it seems a lot of people unwittingly are making this choice which I find both curious and very depressing)
