Former British Prime Minister Gordon Brown has called the deforestation of Sarawak, a sliver of rain forest on the island of Borneo, in Malaysia, "probably the biggest environmental crime of our times. Lukas Straumann investigates that crime. Straumann is director of theBruno Manser Fund, which works to protect tropical rain forests.Speaking from his office in Zurich, Switzerland, Straumann describes the nexus of corruption and weak governance that has allowed Malaysia's timber barons to destroy much of Sarawak's rain forest and export that model to other parts of the world, how his organization is using everything from GPS mapping to the courts to help the Penan people of Borneo fight for their homeland, and what we can do to assist them. Sarawak is a state the size of England—one of two Malaysian states on the island of Borneo, which is the world's third largest island. It also contains one of the oldest rain forests on Earth, which once almost entirely covered the island. But today less than 10 percent of the primary forest is left. Sarawak is one of the hotspots of global deforestation.
