What could cause human extinction?

Some sources of catastrophic risk are natural, such as meteor impacts or supervolcanoes. Some of these have caused mass extinctions in the past. On the other hand, some risks are man-made, such as global warming, environmental degradation, engineered pandemics and nuclear war.

What is the lowest the human population has ever been?

The controversial Toba catastrophe theory, presented in the late 1990s to early 2000s, suggested that a bottleneck of the human population occurred approximately 75,000 years ago, proposing that the human population was reduced to perhaps 10,000–30,000 individuals when the Toba supervolcano in Indonesia erupted and …

What came after dinosaurs?

The good old days. About 60 million years ago, after ocean dinosaurs went extinct, the sea was a much safer place. Marine reptiles no longer dominated, so there was lots of food around, and birds like penguins had room to evolve and grow. Eventually, penguins morphed into tall, waddling predators.

What was happening 10000 years ago?

10,000 years ago (8,000 BC): The Quaternary extinction event, which has been ongoing since the mid-Pleistocene, concludes. Many of the ice age megafauna go extinct, including the megatherium, woolly rhinoceros, Irish elk, cave bear, cave lion, and the last of the sabre-toothed cats.
