Food

It takes more than 40 different species to make a simple lunch (tuna sandwich on whole wheat, potato chips, iced tea, and an apple).

You’d be surprised to know how far some of the ingredients have traveled. As shoppers and as eaters, we play a critical role in shaping what ends up on our plate and why. Informed choices keep us healthy and help protect ecosystems around the world — along with all the species, including humans, that depend on them.
