From the dancing cats of Minamata, Japan, to the swordfish steak at a Monterey fish counter, this video breaks down the 10% energy rule, how mercury climbs the food chain (bioaccumulation), and why the FDA & EPA warn pregnant women and children to avoid swordfish, shark, king mackerel, and tilefish. ⏱️ TIMESTAMPS 0:00 Intro: The Dancing Cats of Minamata 0:42 The Swordfish Steak — A Warning at the Fish Counter 1:18 Three Answers: The Math, The Poison, The Disease 1:52 "Predators Avoid Each Other" — Why That's Wrong 2:48 Answer 1: The 10% Rule — Lindeman's Energy Math 4:35 Answer 2: The Poison That Climbs the Food Chain 6:40 DDT, Bald Eagles & the FDA Mercury Warning 8:05 Answer 3: The Disease Inside a Predator 8:35 Isle Royale — How Disease Left Only 2 Wolves 9:20 Mange, Trichinella & Chronic Wasting Disease 10:00 The Top Predator Is a Filter 10:28 Why Are We Still Serving It?
