predation involves a lot of opportunity. humans have banded together for protection from other animals that are better quipped with teeth and claws for a long time. if someone just walked alone into the Sierra mountains a mountain lion will eventually show up and evaluate how easy it would be to break their spine. we’ve created less opportunities for these predators to harm us if given the chance. arguably our biggest predator is each other bc humans kill a lot more people over a long period of time than a tiger or a bear.
