The doomsday vault is a Noah’s Ark of sorts which would store samples of the world’s important seeds. It was inaugurated at Longyearbyen, Norway. The vault is a trident-shaped tunnel bored into the permafrost of the Arctic mountain range. It comprises three cold chambers and can hold 4.5 billion batches of seeds from the main crops. This is to ensure that plants obliterated by any manmade or natural disaster can be regrown.
