For the past decade or so that I've been aware of peak oil, the limits to growth, industrial agriculture, climate change, etc. I've been wondering something: how did I not know about this stuff before? I'm hoping some of you have wondered that same question.
Of course there are those who were turned onto these ideas early on (say in the 1970s), but by the 1980s when I was born there was little attention paid to them. I'm fairly sure that these ideas (peak oil, limits to growth) will become popular within a matter of a few years just because reality will force people to reckon with them.
So my question is this: what ideas/books/movements that are still at the fringes today that will matter to our future 10 or 20 or 30 years from now? This would be say for the 2020s or 2030s. The seeds of those future ideas must exist now. Maybe some are seeds that will never grow (just as I'm sure there were ideas in the 1970s that died out), but I'm curious what the candidates are - good or bad. I could imagine them being anything from something energy related to biotech to geopolitical shifts to astronomical to something I can't even imagine yet.
In other words, complete this analogy: Peak oil/climate change/etc. is to 1970-2015 as ??? is to 2015-2040.
