I was wondering the same thing, thanks for the stats.

We could get into the nitty gritty and determine how many chickens an average person eats etc, and maybe we'd find that they're actually growing at a reasonable rate in comparison to one another, but at first glance these numbers do suggest that we're killing animals at an accelerating rate.

I'm not vegan but I've greatly reduced my meat intake in the past few years, I only really eat it when I'm out and about. This decision was party made because I care about the environment, but this definitely is not the case for many people, so how could they be convinced? A mass marketing campaign aimed at disgusting them?
