And no, to be clear, the problem is not overpopulation because Earth is not overpopulated.
The problem is a handful of rich countries spending a century building a culture filled with cheap disposable commodities, powered by setting fire to irreplaceable resources and oppression of those more vulnerable. Because a few people decided it was profitable, and lots of others didn't argue because it was convenient.
The problem is that humans are greedy and wasteful, and we need to stop.
(I'll just provide a small correction: "western" civilization teaches humans to be greedy and wasteful
the essentializing humans as greedy has been used for generations to justify not doing anything about it :3)
completely agreed there UwU
The point is not that greed or wastefulness are inherent human traits. They're not. This has been proven repeatedly, and societies would not have formed to begin with if this were true.
The point is that humans did this. We are humans. We can and must undo it.
We can all live sustainably on the planet in a way that allows everyone to have a dignified existence. But it has to be our first priority. Overpopulation is the dog whistle of genocidal maniacs.
