If a raincloud in the airspace over one country drifts into the next one,

is it an illegal raincloud?

What if a pernicious UV photon from the Sun hits a water molecule in the airspace over some unnamed country and splits it apart. Will the two hydrogen atoms, being so light that they drift off into space ... Is that country authorized to go and get them, sort of like (forgive me on this one) a vicious Fugitive Atmosphere Law?

That is really bad.

Perhaps Airspace, Spacespace, and maybe the whole round Earth, which, if you look closely, doesn't have any lines on it at all, should belong to everyone, or maybe the trees and the fish, birds, and whales, because they cause so much less trouble.
