Evolution works fastest during times of great stress and die-off.
Punctuated Equilibrium. Yes, that is quite so. However, biological evolution operates on biological forms (including innate behaviors, of course), not learned cultural ones. Or, at least, it may be argued to indirectly operate on learned cultural forms at a push, I guess, if we include the heritable capacity to learn itself. But, we have a very,
very long way to go down the cultural evolution route of civilizational degradation/simplification before we start to push up against the hard constraints of biological evolution. The problem, here, is in order to get the eco-civilization you are promoting, we would need cultural forms to be available for cultural selection that don't exist in sufficient quantity and, crucially, cant exist in sufficient quantity without further biological evolution of the capacity to be less selfish, less stupid and less cowardly. But, such capacities don't tend to exist in nature because they have either no effect (nature can't think ahead) or have a detrimental effect (nice guys finish last) on biological reproductive success. In other words, they are rarely selected for and are often selected against. We humans evolved our current levels of intelligence, courage and selfishness because of their evolutionary fitness relative to the demands of the environment of our Neolithic and (lower to middle) Paleolithic ancestors. But, as you have said, that evolutionary pressure has since been suspended. We are still middle to upper Paleolithic humans. And it shows, don't you think.

That depends on how far backwards we've gone biologically since natural selection was effectively suspended.
It was effectively suspended at some point in the upper Paleolithic for an ever growing majority of humans. However, the amount of consequent genetic drift that will undoubtedly have occurred in the last, say, eight thousand years is not likely to be significant.
