Humans and our livestock account for 96% of all mammal biomass

100.000 years ago ... 20 mil. tonnes of carbon

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.

I'm good enough with the farm animals Why should I switch to plant based?

I'm not them and I'm not telling you what to do, but meat typically takes ~10x the resources to feed one human compared with plant based food.

Whether you think this means we should eat plants or we should have 10% as many humans is an open question.
