Domestication Dominates – at least among the mammals

Today’s XKCD really gave me pause, so I thought I’d share it with you.  It’s a visualization of the mass of all the world’s land mammals.  Humans are a larger fraction than I expected, and if you add in all of our domestic animals, our entire footprint is pretty huge — but I wasn’t prepared for quite *how* huge.  (Original comic here.)

Alt text with comic: Bacteria still outweigh us thousands to one–and that’s not even counting the several pounds of them in your body.
