Very nice! I would add another stage of defense of alternate foods. If we were actually prepared with these, then I don't think we would get civilization collapse for 1 km diameter and maybe not even for 10 km.

I am now working on an article about submarines as possible refuges in case of a global catastrophe. One of idea I had for food provision for it is filtering of water to get plankton, the same ways as whale do it. What do you think about feasibility of such approach?

That might work, though people would probably prefer fishing. But with a 10 km diameter impact, there probably would not be much fish or plankton.

But may be some bacteria could still be suspended in the water as well as some organics?
