It's probably more fair to say the human economy has surpassed the planet's carrying capacity.
The top 10% of income earners (roughly people making over $40k USD/year) produce half the worlds CO₂ pollution. (And likely also large chunks of plastic pollution and habitat loss due to meat eating)
A world filled with mostly vegetarian humans, with less extractive industry, and transit system built around walking, bikes and transit, would be much lower impact than a world filled with billionaires and their consumer class workers.
There's a long history of the rich who are causing most of the environmental harms blaming the poor who are mostly not responsible to justify ecofascist purges of "those" people.
