A volcanic eruption 70,000 years ago might’ve killed off all but 10,000 humans!

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception 

Today's increasingly destructive natural disasters are troubling. However, they're nothing compared to some ancient disasters, such as the Toba supereruption.

This volcanic eruption took place some time between 69,000 and 77,000 years ago in present day Sumatra, Indonesia.
The explosion is technically described as "mega colossal" and was an 8 on the Volcanic Explosivitiy Index. It deposited a layer of ash 15 centimenters deep over all of South Asia. It was 100 times greater than the largest volcanic eruption in recent history.
The eruption caused a global cooling and decreased the earth's mean surface temperature 3-5 degrees Celsius.
Some researchers believe that it also caused a global ecological disaster that destroyed vegetation and brought on severe drought.
These researchers believe that food sources would have been very scarce and this would have resulted in a severe reduction of the human population - down to just 3,000 to 10,000 people.
