Consider the lives of factory farmed animals. There are some disgustingly brutal things that happen to many if not most animals. However, I think it is an open question whether the average factory animal's life is a net positive or negative. Let's assume, however inaccurately, that all 60,000,000,000ish factory animal lives are about neutral. What are the implications for animal welfare intervention strategies?
First, veganism has no direct benefit to animals. By removing demand for animals, you remove the creation of animals, and so the positive and negative aspects of their lives are both removed and cancel out.
Second, all of those horrible things are still happening, so animal farming improvements are still extremely important and trying to get people to care about animals will still help reduce the bad times and increase the good times for animals.
Are there any other interesting implications?
It turns out Robin Hanson has a short essay on this here and Robert Wiblin responds here. Robin assumes net positive and Robert net negative.
