No, it's merely incredibly difficult. Sustainable living off Earth is far beyond that. Humans definitely can't leave. Humans are even less well suited to interstellar travel than they are to living at the bottom of the ocean, something they also don't do and have no idea how they could ever do. So, with tremendous effort humans could visit one of their neighbouring planets. All of these planets are terrible. Mars is by far more hostile to life than anywhere humans have even visited, let alone had a permanent settlement. But we could do it. To what end? Live here, or die here, those are your options and you should get used to it. |

It's difficult, but I don't think it is _that_ difficult. Ecologies, like any living systems, can self-heal and regenerate. There are practices that allows us to tap into that regenerative power as societies. They may not happen fast relative to our individual human lifespan, but 50 years is more than enough time to restore wastelands or reverse desertification.
I don't have a good answer to how sustain an economy based upon mining, refining, and manufacturing things out of mineral resources. Many of us have gotten used to modern conveniences (at its own cost related to mental and emotional health, and social cohesiveness). I think what most people balk on are on the perception of having to go back to barely surviving off the land, or having to alter lifestyle. Lifestyle may have to change, but the same regenerative power of ecologies also gives us significantly more resiliency.
