The Vaquita is a tiny porpoise that's made headlines around the world because it's on the brink of extinction. Its rise to fame is in part due to one Mexican man, Dr Lorenzo Rojas-Bracho, who's been studying these mammals for over 20 years. His work has put his safety under threat from cartel-supported poachers who work in the areas where the porpoises live. Dr Lorenzo Rojas-Bracho met our reporter, Clayton Conn.
