_As the Nation’s principal conservation agency, the Department of the
Interior has basic responsibilities for water, fish, wildlife, mineral,
land, park, and recreational resources. Indian and Territorial affairs
are other major concerns of America’s “Department of Natural Resources.”
The Department works to assure the wisest choice in managing all our
resources so each will make its full contribution to a better United
States—now and in the future._
