Quick takes

I just saw a video on instagram of someone basically sabotaging megatrawlers by dropping gigantic pieces of marble into the ocean to mess up their nets. People who know about fishing: does this seem like it could be effective or scalable? If so it seems like it could be massively cost-effective.

You probably have heard of this argument, but I just want to point out that it's very unclear whether trawling decreases or increases animal suffering in the short term. It could decrease suffering by reducing wild animal numbers because wild animals suffer a lot. This consideration doesn't make me want to go and eat shrimp or support trawling, but I do think it's good to ask who would be the beneficiaries of such an intervention before pursuing it.
