A new study suggests the Mayan civilization might have collapsed due to environmental disasters:
"'These models suggest that as ecosystems were destroyed by mismanagement or were transformed by global climatic shifts, the depletion of agricultural and wild foods eventually contributed to the failure of the Maya sociopolitical system,' writes environmental archaeologist Kitty Emery of the Florida Museum of Natural History in the current Human Ecology journal."
As we move towards solving the climate crisis, we need to remember the consequences to civilizations that refused to take environmental concerns seriously.
