Why did Mayan civilization disappear?

National Geographic published an article titled: "Maya - a civilization that was Aten". The reason why this civilization collapsed is still unknown. The Mayans in Central America ruled 1200 years.

 

During their greatest glory, the territory had a population density of about the size of today's Los Angeles and a population much higher than any other European country at that time. And then the puff - they slowly disappeared from history. White explorers and conquerors have found only wreckage of the ancient civilization. Here are the reasons for its collapse:

 

Climate change. Large droughts and accompanying disasters impacted the Mayan people.

 

Foreclosure of forests. Giant stone towns, pyramids, roads, and fields. Because of this, the Mayans destroyed their original rainforest. However, full deforestation has caused an artificial change in the environment - the temperature has increased dramatically, the country has been unable to retain water and wood has been missed.

 

Too big of a population boom. If it is true that the Mayans were up to 10 million on this demographic peak, it had to be a huge mass of people. It is possible that the civilization was no longer able to obtain sufficient fertile land.

 

War with neighbors. Maybe it was like ancient Rome. The expansion of the empire at a certain point hit its limit, and then wars only brought worries and high costs - instead of sustainment or gains. On the outside of the provinces, apparently, they began to conquer hordes of "Indian barbarians".

 

Diseases. Mayans were definitely not destroyed from the diseases introduced by Europeans, but could they have been plagued by other epidemics and pandemics? Diseases could also have severely damaged their major crop - corn.
