Check out any certifications you don't recognize or claims that aren't supported before you buy. And be skeptical of "greenwashing" and of unregulated, vague promises like: natural (almost everything is), recyclable (nearly everything can be recycled) or green (what makes it green?). "Free range" means nothing, says Karen Perry Stillerman, a senior analyst with the Union of Concerned Scientists. And "cage free" doesn't necessarily mean that chickens run free.
Research fish choices before you buy. If you can read a paper, you already know that the oceans are being overfished. So skip the varieties with dwindling populations or the ones that are targets for poaching or overfishing. Limit your exposure to mercury and other toxins by choosing smaller varieties of fish and avoiding some farm-raised options. The Monterey Bay Aquarium regularly updates a list of healthy choices, taking into account sustainability and pollution. Or check the Blue Ocean Institute's Guide to Ocean Friendly Seafood.
