Interesting point! I was kind of thinking along the lines of ASuchy, like, I would guess that a big portion of people shop at Walmart? I like your thinking!

Thank you so much!

I don't know! But from putting some things together, to me it doesn't seem clearly related to EA funding?
It seems to me that the first cage-free funding from OP was a million dollars to THL in Feb. 2016. So, there were many fast food commitments before that. Many grocery commitments happened that month and in the next couple months:
February - Target, Trader Joe's, Ahold
March - Safeway, Kroger, Delhaize, Save a lot, Aldi
April - Walmart
June - Grocery Outlet
July - Publix
Someone else would have to say if those were due to changes from the new funding..?

As for quick changes in farming, I think of factory farming as developing pretty fast, but I don't know much about the history! I feel like there's gotta be some other practice that went from 0 to > 50% in less than a decade somewhere at some point :P Thanks again!

I never thought about the "we used to do bad things" part! Thank you for this comment! 

This is very helpful and interesting, thank you for the information! Would most/all of the follow-up campaigns that THL have done be findable online? For instance, when I search stores like "Trader Joe's cage free" I don't find much besides things from 2016, and I assumed that meant that there weren't follow-up campaigns. Is that impression probably right?

In writing this, I was reminded of the possibility of a pretty different corporate ask: pressuring large food companies to invest in animal welfare research or alternatives to animal-derived foods. I'm curious if there's been any recent thinking or doing related to this idea. Procter & Gamble is an example of this outside of the food industry, pressured in part by Henry Spira. In Peter Singer's biography of Henry Spira, Singer catalogues P&G's subsequent efforts to progress non-animal safety testing, which were quite extensive and successful. I don't really understand why P&G kept that going and invested so much into it. Inertia? Pride? Predicted efficiency gains? I don't know, but it seems like it could be good to have in food.

I'm glad this post exists! The first and sixth graph are not showing the same thing; I think the sixth is just North America data?

This is a great question that I hadn't thought of! I will try to find some first-person accounts sometime.

Thank you lots! I like the tipped jobs idea, too!

I agree! I think if I moved I'd have better luck.

This is very interesting! I think one of the most important things here is how much suffering there was of the animals. (Still, I'm also very unsure that less people would mean less consumption would mean less animals suffering.) There's a rethink priorities article about animal farming in Zambia! The video of the chickens did not seem as extreme (extreme as in horrific) as other things I've read about in places like the U.S.
