In case of a global catastrophe, what happens to our plants? What would happen if a plant species was wiped out due to global warming, epidemics, species extinction, or a weather disaster? What if genetically modified seeds contaminate the last strain of an important heirloom crop? Some smart scientists figured out a long time ago that seed banks might save us from ourselves. Like fallout shelters for plant DNA, seed banks are doomsday vaults that protect seeds against natural and human-caused disasters.
