I made a visualisation trying to demonstrate the scale of animal agriculture (and the suffering caused by it). Unfortunately I can't embed it in a post; go have a look at it here.
Interested to hear what people think of it, and whether this sort of thing is likely to be useful as a persuasive tool. It's nothing groundbreaking - just a re-imagining of some existing graphs published by ACE plus some fancy animations. But anecdotally, some people seem to find it quite powerful.
