According to researchers, the civilization disappeared due to climate change.
Harappan (Indus) civilization developed in the Indus river valley in the 3300-1300 BC. According to the researchers, from 2500 years before our era of climate change has led to a gradual decrease in precipitation during the summer monsoon. Winter monsoons, by contrast, has increased, which has negatively affected agriculture and forced the representatives of Indian civilization to move closer to the Himalayas, where the water was less, but the long periods of drought occurred.
The scientists ‘ conclusions were made based on the analysis of bottom sediments off the coast of Pakistan. Researchers have identified fragments of ancient DNA, which can be judged on the income of nutrients in sea water. During the winter monsoons that blow from the land, organic debris rise from the depths of the ocean to the surface, resulting in actively breed plants and animals. In the summer the winds are much weaker.
