Second, some scholars have postulated more-precipitous environmental changes, such as tectonic events leading to the flooding of Mohenjo-daro, the drying up of the Sarawati River, or other such calamities. Third, it is conceivable that human activities, such as invasions of tribespeople from the hills to the west of the Indus valley, perhaps even Indo-Aryans, contributed to the breakdown of Indus external trade links or more directly disrupted the cities. The fourth theory posits the occurrence of an epidemic or a similar agent of devastation. It appears likely that some complex of natural forces compromised the fabric of society and that subsequent human intervention hastened its complete breakdown.]]> 2023-05-01 01:25:18 UTC https://padlet.com/vlt2/ksc0qnhp9arc6zes/wish/2573248605 https://padlet.com/vlt2/ksc0qnhp9arc6zes/wish/2573252053 There was a recorded shift in temperature at around 2500 BC. This caused the weather patterns to change and dry up the monsoons, disrupting the agricutlutre.

The question is, did the trade stop? 
The Indus Civilisation found trade very important, and their main trade source was Mesopotamia. Around the time the Indus Civilisation began to fall, Mesopotamia was going through political problems. This is why people believe trade between the two were declining or ending. ]]> 2023-05-01 01:30:37 UTC https://padlet.com/vlt2/ksc0qnhp9arc6zes/wish/2573253014 https://padlet.com/vlt2/ksc0qnhp9arc6zes/wish/2573253476 This theory suggests that there was an attack on the Indus civilisation from a nomadic tribe called the Aryans. They invaded and conquered the Indus Valley
