Well, I'm thinking this may indirectly be a result of man's doing. Like how we hand out antibiotics like candy, then notice that "superbugs" are
evolving. Maybe something similar is going on, and the smallest organisms are evolving much faster than larger species.
So I think that one way or another, our collective actions are forcing evolution of micro-organisms at an unprecedented rate. I think this is some
sort of critter killing them.
Who knows for sure
