Answer 2

Scientists studying fallen civilizations suggest that the culprit is overshoot in combination with climate change. At the height of its power and influence, the Maya civilization ended abruptly. The population shrank and many cities were abandoned.

By 1800 BCE, most of the mature Harappan sites were abandoned. Around 1200 BCE, this civilisation had completely vanished. The reasons for the end of the civilisation range from climatic change, deforestation, excessive floods, the shifting and drying up of rivers and to overuse of the landscape.
