2 by 2 I guess

Most people are familiar with the story of Noah. He took two of each animal on his ark to save them from the flood. I've always been curious however. What happened to all the dead bodies? In the story Noah and his family, and pairs of animals are saved from the flood. That leaves the rest of humanity and all the other animals to drown. Were they just fodder for the sharks swimming about or did Noah ever see any floaters? And what about after the flood? Did Noah have to spend his weekends burying corpses? Maybe that's what the carnivores ate while the herbivores repopulated. Was it part of the deal? God said, "You can survive, if you clean up the mess." How did he pick which two animals to take? Did he use a lottery or did animals present cases? Well I'm not taking you since you pooped in my yard last Tuesday. There's that cat that scratched me. Forget it Fluffy! The position has been filled.
