"Slash and Burn" Mayan Achievment
They were the first humans to ever create the concept of zero.
How the Mayan Civilization Came to an End
Theory 1, Warfare may have caused the Mayans to disappear because they could have lost a lot of lives during battles. Theory 2, It could have been disease that killed off the Mayans, but where did the disease come from and how did it spread. Theory 3, It could possibly be famine, they probably killed off all their food sources and were forced to separate and starve to death. Theory 4, It maybe was environment change that they did not know how to deal with.
The "Slash and Burn" is a process that will help your soil but after a few times it destroys it. The "Slash and Burn" is when u cut down trees and burn it to when ashes come off and fertilize the grass and crops.
I believe that environmental change is what caused the Mayans to disappear, they were advanced but not advanced enough to protect themselves from harsh storms and other disasters.
