DISCOVER LIFE IN AMERICA T-Shirt. About ten years ago some scientists got together and discussed how cool it would be to identify every species of plant and animal in Great Smoky Mountains National Park. In 1997 they got started and haven't slowed down since. They began the All Taxa Biodiversity Inventory and created the Discover Life in America organization to keep it going. They've already discovered 4,000 new species in the park, and over 500 of them are new to the science books! Help support the effort and look very cool in this colorful T which features native plants, insects, mammals, birds, and a whole lot more.Art by Sally Bensusan of National Geo. fame. 100% cotton, high quality T in "natural" hue.
