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.
In the US, European starlings are one of the only creatures the government pretty much gives carte blanche to eliminate by any means at any time of year.
