Saving Seeds for the Future

Seed banks are a way to preserve seeds and plants (despite the name, many seed banks collect plants and grow the seeds, too) in the event of a disaster, like a war or some kind of climate catastrophe. The idea is to protect biodiversity, as well as food sources, so that we don't accidentally completely wipe out a really useful plant by over-harvesting it, or destroying the habitat where it grows.
The Millennium Seed Bank, which is associated with 250-year-old Kew Gardens, announced last week that they have samples of 10 percent of the world's seeds in their vault. Their goal is to collect 25 percent of the world's seeds by 2020!
