Waterworld
The Atollers offer a trade with the Mariner: if he will stay with them long enough to get one of their women pregnant they will give him all the supplies he needs. The Mariner does not accept their offer. He does not like being around many people. The Atoll's leaders are mad about this. They have him arrested. During the fight to capture him, they learn that he is a mutant. They fear him and plan to "recycle" (execute) him in the Atoll's old dump for domestic waste.
