Any solution that requires 'many generations' is a non-starter.

We've known enough only since the 1970s (according to Buckminster Fuller) to provide for the ongoing success of humanity. There were 30 or 40 years of lag, but steps in the right direction take you in the right direction. And it gets easier as you go.
