- By 2100 – a short 81 years in the future – he sees three potential outcomes: human extinction, the collapse of civilization with limited survival, or a thriving human society.
- The first two outcomes could be the result of population growth coupled with the increasing destruction of our planet.
Besides, Will humans go extinct in my lifetime? (PhysOrg.com) — Eminent Australian scientist Professor Frank Fenner, who helped to wipe out smallpox, predicts humans will probably be extinct within 100 years, because of overpopulation, environmental destruction and climate change.
How Many People Can Earth Support?
Earth’s capacity Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people.
What is the chance of human extinction? However, if AI surpasses humanity in general, then it becomes “superintelligent” and could become powerful and difficult to control. The risk of this is estimated to be one-in-10 per century. These risks combine for a one-in-six chance of extinction per century.
Hence, How can we stop human extinction? Eat less meat, to reduce agriculture’s clear-cutting of rainforests. Never buy anything made from ivory. Adopt a species, or become a “citizen scientist” for a conservation group. Vote for leaders who recognize the importance of conservation and carbon-neutral energy policies.
