We visited photographer Patrick Brown to talk about his forthcoming book, Trading to Extinction, which documents the illegal trade of endangered animals in Asia. We then travel with Brown to Guangzhou, China, where he finishes his decade-long project.

Support the book and find out more about Patrick Brown's project by visiting his Emphas.is page here: http://bit.ly/Trading_to_Extinction
