Negative Population Growth, Inc. (NPG) is a national nonprofit membership organization with over 30,000 members. It was founded in 1972 to educate the American public and political leaders regarding the devastating effects of overpopulation on our environment, resources, and standard of living. We believe that our nation is already vastly overpopulated in terms of the long-range carrying capacity of its resources and environment.
