@Ionus,
What do they have funerals for Io. Bodies are a valuable food resource. There must be nearly 4 million bodies to dispose of in the US in any one year and at 20 stone each that's a lot of meat. All paid for.
Soylent Green. That depicted a materialist society. It had the courage of its convictions. Female companions came with the accomodation and were called "furniture".
I saw a programme which showed a forensic science research project where they buried bodies at different depths and checked them out from time to time. It was to help them establish time of death in murder cases where the killer had buried the victim. It was gruesome and ghoulish to me but I'm a big softie Mummy's boy.
