Seeds and weeds [From the Editor]

It´s sad to realize that there may very well be a need for a seed vault, a facility that stores thousands of different types of plant seeds so that a species can be reestablished if it becomes extinct in its natural environment. Such a vault now exists. Sitting on a remote Arctic island, the frozen contents of the Svalbard Seed Vault wait silently for the revival that we hope isn´t needed.
