Doomer

A doomer is a futurist who believes that global problems of ecological exhaustion — such as overpopulation, climate change, pollution, and especially peak oil — will cause the collapse of industrial civilization, and a significant human population die-off. Many doomers are also survivalists or 'preppers', that is, they are actively preparing themselves for the doom they anticipate.

Peak oil doomers are alarmed that humanity's over-reliance on petroleum for agricultural and industrial productivity will cause severe problems on the downward slope of the peak. By contrast, a "peakist" would be one who takes a brighter view on the implications of peak oil, although this label has been dismissed from within the doomer's movement as vacuous. The opposite of a doomer is represented by a cornucopian, who takes the optimistic position that Earth — and outer space as well — will provide an abundance of resources for mankind to thrive on forever. The middle ground between the doomer and the cornucopian is occupied by the environmental skeptic, who believes that claims made by environmentalists may be exaggerated.

A convinced doomer believes that the Green Revolution will collapse at the end of cheap oil. According to doomers, humanity will be in a state of overshoot after oil depletion makes modern farming methods economically non-viable.
