A destroyed bulldozer is seen at a burned area in the forest at the coastal town of Laguna Verde, some 115 km (71 miles) northwest of Santiago, in this March 6, 2008 file photo. Paying landowners to let forests grow is promoted by the United Nations as a viable way to fight global warming, but experts first have to puzzle out how to insure trees against going up in smoke. Under U.N. plans, owners will get carbon credits to slow the destruction of tropical forests. But fires caused by lightning -- along with other hazards such as storms, insects and illegal logging -- are a big risk for insurers and investors.
