Forests under pressure
Trees provide timber, an invaluable raw material for items such as paper. But they also prevent soil erosion, help replenish the groundwater and are indispensable in climatic cycles, including as CO2 reservoirs. In Germany for example, forested area binds a mere 15 percent of the country's annual CO2 emissions. Nonetheless, 3.3 million hectares of forest are lost worldwide each year.
