Linky please.

The historian in the videos above stated "catastrophic climate change" as the reason which must have been a natural change in the climate for some reason or other.

It is not impossible that humans did cause or accelerate it - they did (arguably) accelerate the catastrophic soil erosion that destroyed a complete civilisation in South America by cutting down the specific trees that held the soil together in the search for larger areas of farmland.
