It seems you can't win with fish.
There are health benefits to eating it, but overfishing is destroying the ocean stocks of wild fish. We're catching more fish than the ecosystem can produce naturally. One anti-overfishing group says the oceans in 1900 contained at least six times more fish than they do today. You can carry around one of those Seafood Watch guides and try to avoid the fish that are red-listed, but most of the green-listed fish are farmed. Fish farming sometimes does environmental damage in other countries, and farmed fish aren't always especially good for you - some of them are fed antibiotics and others are even fed testosterone. So you can go to your fish counter and try to find out whether the tilapia was farmed by an environmentally friendly company like Aquafinca. But that's a lot of work.
