10.000 years ago ... 15 mil. tonnes of carbon
100 years ago ... 10 mil. tonnes of carbon
now ... 3 mil. tonnes of carbon

First 5 mil. tonnes took 90.000 year. Next 5 mil. 9.900 years. Next 7 mil. 100 years. 3 mil. remain, most of the megafauna is already gone.
If we continue this trend, in 30 years there'll be only mice, mosquitos, and medusas. And farm animals, of course.
We have to switch to plant-based diets. Now. There is no other way. No time to wait for technological breakthroughs.
Whether you think this means we should eat plants or we should have 10% as many humans is an open question.
