Richard Vevers has traveled the globe to photograph coral reefs since quitting his advertising job. In 2011 he cofounded the XL Catlin Seaview Survey, a collaboration between the University of Queensland and a number of research institutions, photographing underwater corals as they adapt to climate change. He captured the Great Barrier Reef during its latest—and most devastating—mass die-off, and documented how coral off the coast of Belize had partially recovered thanks to a no-fishing zone.
