This time we get "two for the price of one." Go visit Land Use History of North America (LUHNA) and Colorado Plateau-Land Use History of North America (CP-LUHNA) for a good contribution to your resources on the environmental history of the United States. It goes a long way toward explaining the delicate balance between the viability of our environment and its plant and animal inhabitants and the needs of our human population.

The CP-LUHNA is exceptional in the quality and quantity of material available. These two sites are definite assets to be added to your learning toolbox.

Lifelong learners, enjoy.
