He said: “The human race will become extinct, along with many other species, because of climate change, overpopulation and uncontrolled consumption. » (Fenner, Frank. “The end is so near!”: End of humanity in 100 years! » Daily Star, January 11, 2011.) He believes that the situation is irreversible and that it is too late due to the effects caused on Earth since industrialization. a period known informally by scientists as the Anthropocene rivals any effects of ice ages or comet impacts. Although Professor Fenner formulated a thought-provoking concept of human extinction, a more reasonable idea about human extinction is that it is impossible for humans to become extinct. and his co-author associated with the Global Energy Management Program at the University of Colorado Denver created several scenarios in which humans could become extinct. These scenarios ranged from airborne viruses, side effects of a cancer cure to a full nuclear world war, but concluded that for. For humans to become extinct, "it would have to be the result of some sort of intent, malicious or not, on the part of a group of people, in a place of power on this planet."
