The reasons for the decline of the Mayan civilization are not completely understood, but seem to be related to the destruction of the natural environment. The Maya needed trees to make stucco to cover their pyramids, which lead to erosion, which led to insufficient crops, which led the Maya to build more temples, which continued the cycle. Mayan cities were abruptly abandoned in the 800s. After this point, the Maya civilization became small villages. | The reasons for the decline of the Mayan civilization are not completely understood, but seem to be related to the destruction of the natural environment.
