What Will Happen If The Aravali Hills Disappear?

The Aravalli Hills disappear, the third desert could increase rapidly towards Delhi, Haryana, and Western UP. Heat waves can become longer and more intense, while rainfall would become unpredictable. Dust storms would increase and green cover starts to deplete rapidly. This environmental collapse would directly impact human beings, especially in densely populated urban areas.

How Will The Rising Heat Affect Human Health?

One of the biggest alarming concerns would be extreme heat exposure. Without the cooling effect of aravalli, temperature could go beyond survival limits during summers. This can even lead to:

  • Heat strokes and dehydration
  • Increased case of heat exhaustion
  • High risk of heart attacks and strokes
  • Greater mortality among the elders, children and outdoor workers

Health related death can increase rapidly, especially in cities like delhi and gurugram.
