Doomer

"Doomer" and "doomerism" are terms which arose primarily on the internet to describe people worried about global problems such as overpopulation, peak oil, climate change, and pollution. Some doomers assert there is a possibility these problems will bring about human extinction. Malthusians have related Doomerism to Malthusianism, an economic philosophy holding that human resource use will eventually exceed resource availability, leading to societal collapse.
