  • Is it possible that you’re thinking of slaughterhouse biomass? I was talking about the biomass of concurrently alive animals and I would expect just milk cows to outweigh chickens in a lot of countries.

    My guesstimations are for Flanders, the northern half of Belgium. There’s also a lot of chickens, but pigs + cattle weigh more per animal + live longer, which is why I expect them to weigh significantly more than the chickens at any given time. It’s not sustainable in any way, I read once that about 90% of the livestock food is imported, 2/3rd of that from outside Europe.


  • This is just mammals, so most water creatures aren’t being counted, which is going to be the majority of all animal biomass. So those waters you mention are mostly being ignored, but for living on land and for explaining land usage, just comparing the mammals is more informative.

    I suspect that for my country, if you’d add human + pig + cattle biomass together, that you’d end up with about 99% of the biomass of all land animals. The remaining 1% is probably going to be mostly chickens. Other livestock, pets or wild animals will be lost in the rounding error. It’s only a suspicion though, I can’t find actual numbers straight away.

    Edit: I did find some numbers after all: humans + pigs + cattle are 99.9% of the mammal biomass in my country. It’s actually worse than I thought it was going to be. I can’t find a number for chickens + birds, just the mammals.
