Dust To Dust: A sci-fi thriller short story by the author of False Witness

In the wake of the arrival of the benevolent Arcadians, life on Earth has become idyllic. Except for Del Christensen, that is. His farm is obsolete now that the aliens can make food out of human waste, and his religion is an anachronism in a time when humans roam the stars. Del decides it's time to wake up his fellow Terrans with an explosive statement about their new world and their new Arcadian idols, even if it means he has to die to do it.
