In my debut for Vox, I write about why switching to a pescetarian diet for animal welfare reasons is probably a mistake.
I was motivated to reduce animal consumption by EA reasoning. I initially thought that the moral progression of diets was something like vegan > vegetarian > pescetarian > omnivore. But I now think the typical pescetarian diet is worse than an omnivorous one. (I was actually convinced in part by an EA NYC talk by Becca Franks on fish psychology.)
- Fish usually eat other fish, and they're smaller on average than typical farmed animals.
- The evidence for their sentience is much stronger than I previously thought. I think my credence is now something like P(pig/cow sentience) = 99.99%, P(chicken/fish sentience) = 99%
Given that there are ~30k fish species, generalizing about them is a bit tricky, but I think the evidence of fish sentience is about as strong as the evidence for chicken sentience, something I would guess more people accept.
I also spend time discussing:
- environmental impacts of fishing
- consumer choice vs. systemic change
- shrimp welfare
