The disaster in Uttarakhand has once again turned the spotlight on climate change and its impact on ecology. On February 7, a portion of Nanda Devi glacier broke off, leading to severe floods which washed away villages and damaged power plants. Around 200 people are still missing, and many of them are now feared dead. As per officials, Personnel of the Indo-Tibetan Border Police, NDRF, state disaster response force and the Army have been engaged at the site with heavy earth-moving equipment since Sunday night to clear the tunnel of slush, debris and silt.
