Founder's briefs News

Founder’s Briefs is an occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Rhett founded Mongabay in 1999 to raise awareness about tropical forests and biodiversity. In 2012, he transitioned Mongabay to a non-profit organization and oversaw its growth into a multinational, multilingual news service. Beyond Mongabay, Rhett has advised a range of institutions, while his writing and photography have appeared in hundreds of publications. Rhett's work has been recognized with the Heinz Award and the Parker/Gentry Award, among other honors.
