Planetary pescetarians are fish-eating pescatarians who are laser-focused on sustainability when choosing what to eat. You will not find a planetary pescatarian diving into a dish that includes foods such as Pacific bluefin tuna or skate as they are on the Marine Stewardship Council (MSC) list of fish to avoid due to depleted stocks and overfishing.
A planetary pescaterian might confidently site the MSC’s Good Fish Guide which suggests sustainable alternatives to fish which are in low supply.
