Kaarlo Pentti Linkola (7 December 1932 – 5 April 2020) was a Finnish radical deep ecologist, ornithologist, polemicist, naturalist, writer, and fisherman. He wrote widely about his ideas and in Finland was a prominent thinker. He lived a simple and austere life. Linkola blamed humans for the continuous degradation of the environment. He promoted rapid population decline to combat the problems commonly attributed to overpopulation and was quoted as saying about a future world war, "If there were a button I could press, I would sacrifice myself without hesitating, if it meant millions of people would die." Linkola's writings describe in emotional detail the environmental degradation he witnessed. He dedicated his 1979 Toisinajattelijan päiväkirjasta (From the Diary of a Dissident) to German far-left militants Andreas Baader and Ulrike Marie Meinhof, stating that "they are the signposts, not Jesus of Nazareth or Albert Schweitzer". He supported acts of terrorism such as the 2004 Madrid train bombings as he viewed them as disruptions to a society that is responsible for the degradation of the Earth. When asked in 2007 why he had not himself become a terrorist, Linkola said that he lacked the ability and bravery.
