How Humans Dominate Earth’s Land Mammals

earths land_mammals by weight

Randall Munroe of xkcd, made a chart which shows just how much humans and domesticated animals dwarf what’s left of mammals on land.
There are approximately 7 billion humans on earth — and somewhere in the ballpark of half a million elephants.
While wild mammals are struggling, smaller animals are doing pretty well.
Ants are tiny, but they are in fact so numerous that all the world’s ants weigh almost 10 times as much as all the world’s humans.
Meanwhile, the creatures really dominating the earth are lowly bacteria, which, Munroe points out, “still outweigh us thousands to one — and that’s not even counting the several pounds of them in your body.”
