Transcript of The Decline of the Indus River Valley Civilization

The Fall of the Indus River Valley Civilization
Natural Disaster
There are many people who believe that a storm or natural disaster is what caused the people of the Indus River Valley to leave.
Climate Change
Another theory is that climate change was a major factor in the decline of the Indus River Valley Civilization. The rain that once supplemented the plants began to dwindle as the fertile land started to become the desert that it is to this day. The monsoons that swept the plains moved to another location or stopped altogether. Either way, without enough food, the people of the Indus River Valley would have been forced to leave.
Is this a good explanation? Well, we know that the climate was good for growing crops when these people thrived, and at some point it turned into a desert. But the thing that we are missing is the fact that the change happened at this time, and not any later. Until We find that, there are still a lot of questions to be asked.
Information to Know
The people of the Indus River Valley were very peaceful.
They lived in modern-day India and Pakistan.
At its maximum, the population reached 5 million people.
These people grew primarily wheat and traded with other people for new technology.
The civilization that thrived here suddenly declined around 3700 B.C.E.

What went wrong? What factors led to the decline of the empire and what lessons can we learn from them?
It is possible that the Indus River flooded, killing crops and possibly destroying cities. In fact, this seems very likely, given that a dam caused by plate tectonics was found by the lower section of the Indus River. Also, the area has monsoons that bring heavy rain and wind. Another disaster that may have occurred is an earthquake. After all, there was already movement in the plates by the lower river. It could have ruined cities and farms full of crops, but I don't think that this could have been a cause for evacuating the valley, not by itself. The people of the valley would simply rebuild. There would be no reason to go anywhere else.
Invasion
The first main theory that historians argue about is that an opposing force invaded the people of the Indus River Valley Civilization. Sir Mortimer Wheeler was one of the first to ask if Aryans or some other nomadic tribe had destroyed the inhabitants. To prove it, he showed several skeletons that seemed to have violent endings found in a city and the remains of what seemed to be battlefields and forts. However, there were very few weapons found at any site. Also, the Aryans seemed to have moved into the Valley centuries after the original people left. It seems that if this idea is credible, a group would have intimidated the people before leaving very quickly.
The Mystery
Archeologists have not proved a specific reason for the fall of the Indus River Valley Civilization:
The climate significantly changed to be more arid.
There was a storm or natural disaster.
An invading army or tribe defeated the peaceful people at war.
Historians and archeologists have questioned each theory over and over. Some believe that there were multiple reasons for the decline of the Indus River Valley Civilization, But no one can find a highly credited reason to explain for this great loss.
We can learn many many things from the past. In the situation of the Indus River Valley, we can learn two big ideas:
Never leave yourself unprotected and vulnerable.
Be prepared to adapt.
