I'm not really sure what you mean by "unfit for humans". If you're talking about the problems we are creating for ourselves as a result of the unforseen/long-term effects of our "progress", I think these are inevitable. And even though many of these things exist, there are groups who are aware of them and choose to exclude themselves from those activities. I'm no sociologist, but I think groups of people organize themselves around common goals. The problems which are the most mainstream will get the most attention and support for corrective action. As well developed nations remove these common problems, people are less incentivized to participate in quorum and will do their best to fulfill their own desires to whatever end. Not sure got to your question.
