Bao Xishun, the World's Tallest Man

Environmental Hero
In December, 2006, veterinarians at an aquarium in Fushun, China, called upon Bao to help them save two dolphins who had swallowed shards of plastic. With his long arms — they are 41.7 inches, or 1.06 meters long — Bao was able to reach into the dolphins' stomachs and retrieve the shards.
