Mineral resources and conservation in Texas

The conservation movement has grown enormously in strength and breadth during the last decade as a result of widespread concern about natural resources and the quality of the environment. The Federal leadership broadened the definition of conservation to applied ecology and thereby put a meaning into the word that went far beyond its original sense. Conservation now includes all of the physical, social, and legal problems attendant on use of the land. The inclusion of a wide variety of environmental problems under the umbrella of conservation caused a great deal of pushing and shoving of traditional "conservationists" to make way for the new "environmentalists." Broadening of the conservation movement to a total-environment movement has brought many new people into it--scientists, engineers, economists, geographers, and ecologists--people that are professionally concerned with the environment on a working-day basis.
