Mayan Theories

When the Mayans moved to the Yucatan Peninsula, there wasn't any water there. So they had underwater rivers that flowed to make underwater caves. My theory for how the Mayans collapsed, is that the rivers ran dry. Which leads to them not having any water to say grow crops, bathe, or even have water to drink! So when all the water in the village was gone they started to die out. That is my theory of how the Mayans collapsed.
