Why do certain species of plants, birds and animals become rare? Are all rare species on the verge of extinction? Which species that are common today will become rare in the upcoming years? These are just a few of the complex questions about the nature of rarity that ERIC DINERSTEIN attempts to answer in his new book THE KINGDOM OF RARITIES. Eric Dinerstein is the Chief Scientist for the World Wildlife Fund, where he has spent the past 24 years working to save rare species around the world. Tune in tonight for an informative and fascinating look into the lives of creatures like the jaguar, the one-honed rhinoceros of Nepal and the Kirtland’s Warbler of Michigan.
