The focus of much dialogue and debate in the public eye over climate change and greenhouse gas emissions (GHGs) tends to focus on industrial emissions of pollution for manufacturing or the production of electricity. Emissions from transportation sources (like trains, planes, and automobiles) and from the heating, cooling, and lighting of buildings themselves are less readily visible, yet each constitutes roughly a third of America's total greenhouse gas emissions.

The federal public lands—national forests, parks, and rangelands—are widely known for their vast natural resources: timber; range; minerals; watersheds; wildlife; and sweeping vistas of incredible beauty and diversity. No less notable are the cultural resources found on the public lands. Some of the earliest withdrawals of public lands from homesteading or other disposition occurred because of their cultural and historic importance.
