And it’s not just about climate change. It would be far more straightforward if it was. It’s also about depleting the planet’s resources (and how that will play out geopolitically and militarily when they start to run out), overpopulation, polluting the air and the oceans, devastating wildlife.
Reducing the debate to climate change is insanely simplistic.
I personally think the climate change part of it is not the most consequential for us, or the planet. The planet will recover from the effects of climate change eventually, but possibly not from the impact of our consumption if it goes on for long enough.
