[00:00:00]There is a lake in Africa that kills sleeping people in the night. On one night in 1986, 1,700 to 1,800 people from three villages near Lake Nyos in Cameroon died in a single night. No earthquake, no flood, no attack. In the morning, people were found exactly as they had fallen asleep, dead. The reason? CO2 that had been building up at the bottom of the lake suddenly released all at once. This gas is heavier than air, so it spread low across the ground in every direction. The sleeping people never felt a thing. The gas spread up to 35 miles. Not just humans, livestock, birds, and insects all died. The lake still exists. CO2 is still accumulating at the bottom. Scientists have installed pipes to slowly release the gas.
