You really think you're going to convince people to become poorer? Not possible in a democracy. It'd require some kind of ecofascist totalitarian thing where you take peoples' energy and resource use away and fire tear gas and rubber bullets at them when they protest.
Or we could build non-carbon-based energy sources. Cause we have those, and they work. You can also have safe sex if you put a rubber thing on your wing-wong.
That’s correct and eventually that will have to happen. There aren’t much other actual options. It’s mostly a question of how long that can be avoided. We developed a system that blocked us in the current local optimum, with no ways to take the drastic actions we need to handle global issues like climate change.
(And to be clear, an ecofascist regime would be horrible to live under)
No, we couldn't, because degrowth solutions aren't really an option.
