I concur. Outside of waste heat and carbon dioxide, at least on this
planet, it is a recognised pattern that as a society becomes more
advanced economically and technologically past the early industrial
stage, the per capita amount of waste and pollution produced goes down.
The turnaround point is somewhere around a per capital income level of
$8,000.00 per year. Once you get to that point as a nation, your average
personal pollution goes down.
Extrapolating this, considering that gamma rays are about the nastiest
form of pollution one could produce, I highly doubt that a highly
advanced civilization would be party to widespread pollution of parsecs
of space by gamma ray bursts.
