Earthworks

In a future where the Earth has been savaged by overpopulation and over-farming, robots are considered more valuable than humans and sand must be altered to create artificially fertile soil. Ex-convict Knowle Noland, the hallucinating sea captain of the Trieste Star, finds himself wrapped up in a plot to incite a global war that will wipe out millions. War, it seems, is the only way to drastically reduce the population and create a better world for those who survive.
