I’m somewhat of a skeptic when it comes to seafood sustainability. I doubt that any fish farming endeavor is completely waste-free or low-enough-ecological-impact to be done at the scale that would be needed to wean our culture off of a meat (and soy) industry that is tearing up the planet. You may not be aware, but much of the deforestation in South America is either for cattle raising or soy bean production. Much of the soy being grown is exported to be used as livestock feed, not for direct human consumption.
However, I do still think that it is necessary for most humans to have some animal protein in their diet (because our bodies have evolved this way). By “some,” I mean about the size of a deck of cards per week per adult. That is really all anyone who isn’t training or super active needs. (But of course, our tendency to want everything in excess defies self-control or self-denial.)
