Malthusians has been sounding the alarm for longer than Protestant revivalists have been claiming the end of world is next month at lunchtime. If there is a predication market for such things, betting on any Malthusian is patently foolish.
(Of course, I don't disagree with the notion that consumerism produces an extraordinary amount of worthless trash, but that's a different matter. The main problem with consumerism is consumerism itself as a spiritual disease; the material devastation is a consequence of that.)
People gloating about Malthusians being wrong keep forgetting that it only takes for them to be right ONCE in the entirety of human history and when they are - you'll be too busy trying to survive rather than posting on internet forums.
The planet has a certain resource-bound carrying capacity. It's a fact of physics. Just because we aren't there yet as of (checks time) 2026-03-27, doesn't mean Malthusians are wrong.
Although to be fair to the other side, I think with abundant renewable energy we'll be able to delay resource depletion for a very long time thanks to recycling (and lower standards of living of course).
