Not judging but just relaying. I used to be like this--ate fish only. But then I read a comparison that what we're doing in the oceans is much worse than what we do to land animals. In the ocean, we kill and kill--with no rejuvenation of the population. That is destroying species of fish. We're basically at war with the fish and the fish are losing.
At least with cows, pigs, chickens, and other farm animals, we perpetuate the species we're eating.
