Wild mammals are a rounding error

Weigh every mammal on Earth. Livestock take most of the mass. Humans take most of the rest. Everything that still lives wild — whales, deer, rats, bats — shares the last sliver.

Greenspoon et al. 2023 (PNAS): livestock ≈630 million tonnes, humans ≈390 million tonnes, wild mammals ≈60 million tonnes (about 20 land + 40 marine). Shares rounded onto 1,000 equal cells. This grid is mass, not headcount — one blue square is the same tonnes as one orange square.
