I say this because climate change and the Holocene extinction are going to be a lot worse than people realize. There is going to be more disease, more fire. Capitalism's rabid growth and consumption has started hell on earth. That's not cope, I don't actually want it to happen that way because it's not just the US that will collapse, it's all of us, humans, animals, plants. That's my opinion as a training ecologist. It is so much worse than what they're telling you.
This isn't just about economics or war anymore. There are different forces at play than with other falling empires.
