Some scholars debate that the actual cause for the mystery in the Indus Valley is environmental stress, like climatic change. According to evidence cited with the ancient civilization, the Indus Valley Civilization necessitated a wet environment to supply all the materials needed for the society to grow and prosper. After a millennium, the wet environment in the Indus Valley shifted to a drier environment, which pushed the ancient civilization into a downfall. In fact, researchers believe that the dry conditions began in a period in the second millennium BCE. Other evidence that supports the viewpoint of environmental stress as the cause, includes the shifts in the routes of many rivers that served as main water sources. The changes in the routes occurred mainly because of tectonic forces acting on the surface of the Earth, like earthquakes. Once the old routes of the shifted rivers dried out, the result would include many issues and obstacles for the people settled near the area. Some of the issues faced by the Indus people include, the loss of arable land, the decline in food production, the relinquishment of successful cities, the movement of populations away from the valley, and the rivalry for limited resources. Altogether, if the natural events stated above acted on the Indus Valley Civilization, …show more content…
Maybe the answer is hidden within the unique writing system of the Indus script, but until a team deciphers the scripts, many reasonable debates concentrate around the puzzling ancient Indus Civilization and give excellent and comprehensive evidence that greatly supports their
