Explanation:

Perched at the height of 17,300 feet above sea level, India’s doomsday vault lies in Chang La (a high-altitude mountain pass in Ladakh) and is the ultimate insurance policy for the country’s food supply, offering options for future generations to overcome the challenges of climate change and population growth. Built jointly by the Defence Institute of High Altitude Research (DIHAR) and the National Bureau of Plant Genetic Resources (NBPGR) in 2010 under the aegis of Defence Research and Development Organisation (DRDO), this permafrost seed bank is the second largest in the world. The idea behind this invaluable vault is to safeguard the world’s flora from global catastrophes, both natural and man-made. For instance, if nuclear war, coastal inundation, prolonged drought or plagues of pests leads to extinction of crop species in the future, governments will be able to request seeds from the vault to revive their agricultural sector.
