If you’ve ridden BART his month, there’s a decent chance you spotted a new ad that’s meant to prick the conscience: an image of happy piglets frolicking in an open field juxtaposed with a shot of a few sickly-looking pigs locked up in cages.

“95% of people want farm animals to be treated well. 99% of farm animals are not,” the tagline reads. “Help end cruelty by participating in Meatless Mondays.”
