Why did the Maya Disappear?
Source: Why did the Maya Disappear? by Luke Caverns

Archaeological evidence shows Maya cities like Copán faced significant environmental stress, but research on Copán is debated. Studies suggest deforestation may not have been the primary cause of its collapse. Research indicates drought was a major factor across the Maya region. The paint pigment contamination claim at Tikal and Calakmul lacks support in available archaeological literature.

Key facts

  • At Copán, Honduras, archaeologists found the city was completely deforested during its height
  • Maya cut down all trees to obtain wood for stucco plaster and construction
  • Deforestation created a miniature climate crisis with no rainfall on farmlands
  • At Tikal and Calakmul, paint pigments were seeping into water supplies and poisoning the population
  • Water became non-potable, forcing cities to be abandoned
  • When crops failed, entire cities packed up and deserted simultaneously
