03 Β· The living scale
Who weighs the most on Earth?
The total living weight of every animal in each group. Each cube is 1 million tons of living animals.
π Farm animals (cattle, pigs, sheepβ¦) weigh 29Γ more
Figures are rounded global estimates of living (fresh) weight (Greenspoon et al. 2023, Bar-On et al. 2018). Uncertainty is large for wild animals.
