What is the Cornucopian idea? What do Neo-Malthusians think of this idea? What is the Cornucopian idea? What do Neo-Malthusians think of this idea? Cornucopians believe that economic incentives produced by supply and demand will lead to innovations that solve environmental problems such as food shortages. Neo-Malthusians argue that the Cornucopian idea incorrectly assumes that population growth and economic growth can continue indefinitely. The main Cornucopian idea is that birth control will lead to relatively high food security by reducing the need for constant technological innovation. Neo-Malthusians critique this idea because it does not include strict limits to population growth. Cornucopian theorists argue that Thomas Malthus' ideas were incorrectly based on moral judgments about poor people, and neglected the importance of education in agricultural productivity. Neo-Malthusians acknowledge that the original Malthusian theory included moral judgments, but that new Malthusian ideas are based solely on understanding population biology. Cornucopian ideas include an emphasis on the "invisible hand" of the free market as a preventative check on population growth that also affects agricultural productivity. The Neo-Malthusian critique of Cornucopian thought emphasizes the possibility of indefinite population growth
