I was told to shorten my question to a number of different questions altogether.
Let's say that WR-38 blasted Earth, what would happen to the surface of earth?
More specifically, how would the changes to the ozone layer effect the surface? Perhaps this could cause smog on the surface, or maybe it leaves an enormous pit from the radiation burst. How would the surface differ after the shock of a GRB?
What would the surface of earth look like if a GRB ruined the ozone layer? In other words, what are implications for surface life post GRB hit?
