by Emily Cassidy and James Gerber, Ph.D.
Southeast Asia is one of the most carbon-rich places on Earth. The region is home to dense tropical forests, as well as peatlands and mangroves, which together store massive amounts of carbon above and below ground. But when trees are cut down and peatlands are drained, these carbon stores are released into the atmosphere.
