Sarah Schumann gave an interesting presentation at TED Providence. She argued we should all choose seafood like a fish. Eat anything you can. By being an opportunistic predator people stop targeting one species until it crashes and disrupts the ecosystem. Instead we end up eating the most common which balances the seas. We figured this out long ago during our Catch-M-All Quest to catch and eat every kind of freshwater fish in New Hampshire. Fishing in the food web.
She concluded her talk with a bit of prose. Good for her.
