Between 1975 and 2019, nearly 8% of the Aravali hills have disappeared, says a study of the ranges across four states, projecting the losses to rise to around 22% by 2059 if "explosive" urbanisation and mining continue at the current pace.
Over 30 hills in the upper Aravalli range have completely vanished in the last 20 years. Additionally, "hundreds of hills" have been flattened to lower and middle levels., Delhi News, Times Now
