Doomsday vault

We keep seeds for thousands of species and varieties of plants in the Doomsday Vault.
Should disaster ever come, future generations can recover these plants.
I walk across the frozen tundra, enter the vault lobby, and open the hatch.
I close it behind me before I descend the stairs.
Another hatch, another set of stairs, and then… the vault.
I quickly find what I am looking for…
Brussels sprouts.
I grab all of those seeds and return to the surface.
And dump them in the lake.
It’s bad enough we will destroy the world.
Why make future generations suffer more?
