Seeking to help fight climate change, the Walt Disney Co. says it will spend $7 million in partnership with three conservation groups to protect tens of thousands of acres of forest lands in the Congo basin, the Amazon basin and in two regions of the United States. The company will work with the Nature Conservancy and provide $2 million for tree planting on 2,000 acres of former forest lands in the lower Mississippi Valley, and $1 million for the Conservation Fund's forest protection project along California's North Coast.
