In the meantime, the american grey squirrels are invading Europe, taking over the whole continent, driving the local ginger squirrels to extinction, spreading diseases and pests like ticks.
I was just thinking about this the other day when I saw a gang of squirrels trying to murder each other while another fat ass drug a slice of pizza up a tree.
I have my doubts about the methodology on the state per state breakdown. Michigan is all forests once you get north of Flint, so there is no way yhe squirrel to human ratio is less than 4:1. Same with Ohio
It's because this is basically a human population map (with the exception of Hawaii), no? Michigan and Ohio are still very populous states, so it offsets the squirrels.
