Source?
Im gonna go out on a limb and say this is udder cowshit. Rats are mammals, as are raccoons, squirrels, and whole fucking masses of little basically unfarmable varmints. You're telling me that there's like 12 farm cows for every wild rat on earth?
Horse. Shit.
The source apperently takes the percentages by biomass, not by count as it seems. So small varmints will not have as much of an impact as a human or cow would.
in the comments section. straight up 'sourcing it'. and by 'it', haha, well. let's justr say. My pnas.
Which I think is intentionally disingenuous as it massively favours the large mammals over the far higher number of species of smaller mammals.
For example you'd need over 70 squeal monkeys to make to the biomass of an average American.
Humans and other great apes can be considered mega fauna, so it doesn't seem surprising that us and the animals we consume make up a higher percentage of bio mass. Were bigger.
I don't think it's disingenuous. It represents the total share of resource consumption. If something has 2x the biomass, it consumed 2x the materials needed to produce that biomass (purely in terms of the makeup of the body, that is)
I don't think count by itself is very relevant. There's more bacteria in a glass of water than there are humans in a country, but what does that tell you, exactly?
Although I do agree the infographic should be changed to specify biomass

Quick Internet search.... https://ourworldindata.org/wild-mammals-birds-biomass
They are referring to biomass.
-
1 cow ~ 1200 lbs / 545 kg
-
1 rat ~ 0.5 lbs / 0.25 kg
1 cow ~ 2400 rats by biomass
Well thats not what the infographic says. It specifies "mammals", not "mammals by weight".
OK so how many tons of cow are accounted for by whales?
Or does the survey cherry pick land animals too?
Not saying at all this isn't a problem, but I hate bullshit statements that are deliberately deceiving.
These numbers are all by mass. Not actual number. Cows are huge. So are chickens, for birds. How this comic is laid out infers that there's 60 cows for every 40 of every other mammal, and that isn't even remotely close to true.
I think biomass is probably more important than sheer number for these comparisons. Although I would also accept 'proportion of world's arable land being used to sustain them' as I suspect the ratios come out pretty similar for obvious reasons.
The problem is that the infographic says "of all the mammals on Earth", which means individuals, not biomass. So the infographic is objectively false.

I don't think this is loss. I'm ready to eat crow if I'm proven wrong, but I think the real joke is the amount of time people will spend staring at this image and trying to figure out how it's loss
You forgot the citation bro.
It's by biomass.
It's from this article: https://www.theguardian.com/environment/2018/may/21/human-race-just-001-of-all-life-but-has-destroyed-over-80-of-wild-mammals-study
Which is discussing this research: https://www.pnas.org/doi/10.1073/pnas.1711842115
By mass.
Title made me think they were doing some 4 levels deep "loss" meme. It almost has it but frame 3 isn't close.

Are pets livestock, or did they miss a category of mammals? In the US there are more dogs than children.

birbs are only 2/3rds unreal confirmed ✅
I didn't realise rhinos were so small. No wonder I never see them.
End of the Holocene, Last of the Megafauna party.
It’s so fucking surreal to me how much megafauna extinctions have happened in the past 50’000 years.
I don’t think people realise we had like giant land birds (3+ meters tall), megasloths (elephant sized), giant kangaroos roaming round not that long ago.
The garden burned. We were best adapted.

(In many places, we burnt the garden).
We’ve been shaping ecosystems through fire for so long.
That article’s on my to read list now, thanks.
