But the genetic diversity contained in the vault could provide the DNA traits needed to develop new strains (39)

whatever challenges in the future. This is particularly important with the challenges of climate change.

“Not too many think about crop diversity (40)

something so fundamentally important, but it is. It is by no means less important than water or air“, claim the scientists.
