The Maya civilization may have collapsed due to lack of resources

The builders of the ancient Mayan temples at Tikal in Guatemala switched to inferior wood shortly before they abandoned the city in the 9th century AD. The change is strong evidence that Mayan civilization collapsed because they ran out of resources.
Researchers led by David Lentz, a palaeoethnobotanist at the University of Cincinnati in Ohio, sampled wooden beams and lintels from all six major temples and two palaces within the ancient city of Tikal. The first three temples, built before AD 741, used only large, straight logs of the sapodilla tree – a particularly strong wood that is nevertheless easy to carve with ceremonial inscriptions.
But after that date, large sapodilla logs were almost entirely replaced in temple construction by logwood, a smaller, gnarly tree that is almost impossible to carve. “It’s definitely an inferior material,” says Lentz, who reasons that the temple-builders would only have accepted logwood if they had run out of suitable sapodilla trees to harvest.
