A doomer is someone who believes that the global problems of ecological exhaustion—such as overpopulation, climate change, and pollution–will cause the collapse of civilization, and a significant human population die-off. They are alarmed that humanity's over-reliance on petroleum for agricultural and industrial productivity, along with government inaction will cause severe problems. Climate change deniers takes the optimistic position, with regard to ecological matters at least, that the Earth—and outer space as well—will provide an abundance of resources for humankind.
These individuals believe that the agriculture will collapse at the end of cheap oil, and that humanity will be in a state of overpopulation after oil depletion makes modern farming methods economically non-viable.
Paul R. Ehrlich and the Club of Rome's ideas about population growth are a possible influence here, as are some of the more recent works by Joseph Tainter who wrote The Collapse of Complex Societies in 1988, and Richard C. Duncan who presented his Ph.d. The Peak of World Oil Production and the Road to the Olduvai Gorge in 1989 (now known as the Olduvai theory). Ehrlich has been criticized for his opinions; for example, Ronald Bailey termed him an "irrepressible doomster". However, Carl Haub observed that Ehrlich's warnings had encouraged governments to change their policies to avert disaster. Ehrlich has acknowledged that some of what he predicted has not occurred, but maintains that his predictions about disease and climate change were essentially correct, and that human overpopulation is a major problem. Prof. Albert Allen Bartlett's work has been highly influential. As one example, his work on exponential growth and population is referred to in depth in the Crash Course created by Chris Martenson and his organisation Peak Prosperity. His lectures and a DVD, Arithmetic, Population and Energy are important (see below for online video streaming of the lecture he has been presenting and refining for over 30 years).
The common concerns are that overpopulation will lead to resource and energy depletion, soil degradation and environmental destruction, all culminating in agricultural collapse and famine.
