"Sucking fewer resources for a longer time" in a manner that preserves our ability to innovate new resources is the best we can do.

If that's the best we can do.....fine, but don't be surprised if it isn't enough.

Just because the current political atmosphere assumes that transportation costs don't matter, there should be no restrictions on trade, trade balance doesn't matter, currency stability doesn't matter, there is always a military backup, et cetera, et cetera... doesn't mean that the falsity of those things invalidate trade in general.

There is nothing wrong with fair trade, cooperative behaviors, and currency PER SE, but allowing them to become the unrestricted competitive mores of our existence was what killed us.

If need be, we'll mount sails, batteries, and solar panels on our freighters before we stop using them altogether due to environmental reasons or fuel scarcity.

And the banks will loan you the money to do so, and you will waste even more resources to pay them interest so that you can feel like you've 'accomplished' something 'technological' while Nature uses her technology to decay your solar panels, to decay your body with the poisons you put into the atmosphere, to cause defects in the stem cells of your children because you thought pesticides and plastics were a 'fair' tradeoff in order that you could make a 'profit' or be entertained by a better TV.
It all comes around, and now it's coming around now, so go ahead and build your electric cars, your solar sailing ships, your solar powered aircraft carriers and missile-firing drones, and your satellites to watch us all f>>king die in hand-to-hand combat with the solar powered wolves (or in detention camps at the rate our voters are going).
Optimism disgusts me, my chickens, and my longevity-limited children.
