Why do historians think the Maya declined?

Historians believe the decline of the Maya civilization resulted from a combination of factors, including environmental degradation, prolonged drought, and social upheaval. Intensive agricultural practices may have led to soil depletion, while climate change could have caused severe droughts, exacerbating food shortages. Additionally, internal conflict and warfare among city-states likely weakened their political structures and social cohesion, contributing to the overall decline.
