There's no finite environment in an infinite universe. We are not anywhere near utilizing even 1% of what's available on this planet.

growth can also mean efficiency increase, not only "expansion". I rember that Japan is the most efficient society in its use of inputs at around 20%. there is enormous space for growth

According to dipshits like Jeff Bezos they want trillions of us living in space on stations like house cats.

Saying it in a situation where we don't utilize even 1% of available resources. Much closer to 0.0001% than 1%.

Also saying it in a situation where we don't even really attempt to be efficient.

Now I'm all for efficiency - but that's not what the degrowth people are saying.

The number of people who've read LTG and think the world3 ressource usage predictions are accurate is crazy. The authors themselves say it's not accurate and overly simplistic.

By very far the threat to humanity is global warming, not resource depletion.

A lot of degrowthers want resource depletion to be very important because that's the only way what they call "green capitalism" doesn't work, but that's not fact-based.

Sadly for them basic pigouvian taxes + subsidies to innovation + reasonable behavioral changes (due to taxation) will mitigate most of the problem. That's completely compatible with what they despise as "green growth".
