I'd rather die than eat a human.
Me too. Besides I am sure that if ever you will be placed on that situation you will find a way just to survive. You will not make option to eat human just to survive. There are plants and animals that are edible. Let just focus on the plants for sure there will be plants around you that can be eaten. If you are in the place near the sea, snails, crustaceans and the likes will be your meal.
"There are plants and animals that are edible". In isolated locations that are nowhere near anything liveable, are you sure about that? You can't just assume what you would do in such a situation because if it were so we'd ever have the stories like the plane crash at the mountain that was extremely cold and had nothing living on it. No plants and no animals. They ended up eating the ones that died and thus survived until rescue came.
