Our Heroes: Shana Miller, Tag-a-Giant

When she was in college, Shana Miller spent a summer on Martha's Vineyard fishing for her dinner because she didn't have enough money to buy food. Food insecurity gave her a greater appreciation of the ocean environment, and eventually led this would-be primate scientist to a career saving one of the ocean's top predators, bluefin tuna, which are in danger of being overfished.
