Have you ever seen one of those ads with a celebrity like Jackie Chan or Leonardo DiCaprio beside a beautiful, rare animal? If so, there's a good chance it was promoting a WildAid campaign. This week on Sea Change Radio, we speak with the CEO of WildAid, Peter Knights, about the organization's mission to protect endangered species. We explore the challenges of trying to globally ban the trade of ivory, discuss the methods they use to curb the demand for rare animals (particularly in China), and hear an update on the status of the totoaba, a rare fish whose bladder is sometimes referred to as "aquatic cocaine" because of the astronomical price it fetches on the black market.
