Why Do We Eat Tuna But Not Lions?

Why do we eat tuna, salmon, and swordfish, but not lions, wolves, or bears? The usual answer is that humans do not eat predators. But tuna is an apex predator, salmon hunts, and even farm animals eat other animals when they get the chance. The real answer is hidden in the economics of the food pyramid: energy loss, who pays to build each level, and what accumulates at the top. This visual explainer follows the ninety-percent rule from grass to lions, then into the ocean, where wild tuna arrives with its entire food pyramid already built. It also explores the ecological bill, mercury biomagnification, polar bear liver, and the one major predator humans deliberately farm.
