Human nature does not change in the short term –our great-great+ grandchildren living in 200 years will be subject to all the same drives and constraints I just mentioned. But culture can manifest emergent behaviors –both positive and negative– that can happen on much shorter timelines, even less than a decade in some cases. Our genes tell us what we need, but culture dictates how we get it. We can get at least a good portion of ‘what we want and need’ using less stuff with less damage.
