Water Crisis: Displacement Estimates and Future Conflict Concerns

The claim that future world wars will be fought over water is supported by multiple sources, which discuss the potential for conflict arising from water scarcity and climate change [1][4][5][8]. The assertion that civilizations have historically developed along rivers due to the essential nature of water for survival is also a widely accepted historical and geographical fact, mentioned in the context of ancient civilizations and their reliance on water sources [4][10].

The idea that the water crisis is an impending catastrophe that will disproportionately affect India is also supported, with sources highlighting India's significant water stress and the potential for severe scarcity [1][7]. However, the specific claim that 120 million people are estimated to be displaced due to the water crisis, with 80-90 million of them being Indian, is not directly corroborated by the provided sources.

One source estimates that as many as 700 million people are at risk of displacement by 2030 due to drought [9]. Another source projects that by 2030, India's water demand could double the available supply, potentially displacing hundreds of millions of people [7].

While these figures indicate a large scale of potential displacement, they do not match the exact numbers provided in the claim. The claim about the video showing specific imagery is not verifiable from the provided text context. [1][2][3]
