I don’t believe humans should operate as pure, replicators– doing any action for the chance to continue to exist. Fishing is global and global fishing runs on slave labor. I am doing them a favor. It’s called ethics for a reason. You are presented with 100 things you can eat. Seafood and cocaine are probably the most unethical. Why not skip them?

Not in the short run but in the long run everybody would win. If you lower demand I assume people would find another way of living that would be more sustainable.
