The most severely affected areas in the U.S. are in New Mexico, Texas and on the Navajo Indian reservation in New Mexico and Arizona. The United States is firmly committed to implementing the CCD. Better known as “buried soils,” the featured soils contain secrets of the climate, ecosystem, and fossils of the Earth’s prehistoric past. In the United States alone, it is estimated that 12 million barrels of oil are used annually to make plastic bags [1]. In addition, it addresses policy issues with regard to economic and environmental impact, land use change, and global trends. His message is simple: Although the United States has some of the richest soils in the world, decades of agricultural abuse have taken their toll, depleting the dirt of essential nutrients and killing off bacteria and fungi that create organic material essential to plants. How does the severity of soil degradation in the southeast compare with that in the plains states from Texas and the Oklahoma panhandle up through Kansas, eastern Colorado, Nebraska, and Iowa to the Dakotas?
