The arctic seed bank that was going to save us all is flooding

It’s cool, isn’t it? Looking at various images, the look changes a lot with time of day, and maybe time of year.

I’m curious about the plastic tote boxes holding all the seeds. Wondering, e.g., how stable the plastic is—e.g., does it off-gas? How well will it age—will it become brittle, or deteriorate in some way like so many household plastic items? There are umpty-million kinds of plastic…I imagine they chose carefully; it would be interesting to know how they chose.
