If we insist that "we're all in the same boat", we shall all drown, because the one boat will sink. Those who hope to preserve civilization must accept that it is likely to sink into chaos in much of the world. The survival of some elements of civilization will require lifeboats that can be constructed only from communities, regions, perhaps nations, that are not now in overshoot. To preserve civilization at least some of these must choose to stay out of overshoot, establish independence in the production of food, energy, materials, and crucial manufactured goods, and defend their borders against the migrations that will tend to spread overshoot everywhere.
I've argued before now that we may need to move away from the "efficient" way to do things, towards the survivable way - click on the label below for some notes on what I call "Diversity, dispersion and disconnection."
