At its height in about 800 AD, there were probably about 13 million
Mayans supporting elaborate cities with grand pyramid temples. But almost
instantly everything collapsed. Researchers have recently discovered
that it was in fact climate change that caused the collapse of Mayan
culture. The worst drought lasted between about 760 and 800 AD. Each of them
put more intense pressure on the already fragile civilization. But they relied on corn-growing farmers who didn’t produce enough to sustain both themselves and the city dwellers. Their
land had fast rivers being mostly dry which was crucial for the survival of Mayan
Civilisation. People
will have to change their habits even more, in order to survive the
climate changes that are predicted in the next decades.
