Here is an example of how conservatism with regard to taste is harming us. As this article by Sea-to-Table argues, 91% of all seafood consumed in the U.S comes from outside the U.S. and two thirds of that is shrimp, salmon, Tilapia, and canned tuna, much of it farmed under less than sustainable conditions. We eat the same stuff over and over.
Yet U.S. waters contain hundreds of species of seafood, such as pollock, mullet and dogfish, that taste good and have not been over-fished. If only we could overcome our reluctance to try new things.
Chefs will have to take the initiative
