Simple- don’t go where bears/mountain lions/sharks are and you won’t be attacked. They don’t come to your house(except rarely in remote locations). Our ancestors worked HARD to get out of the wilderness and make civilization. They fought off bears and all manner of hostile animals dreaming of not having to.They would think people like this are nuts to wander around the woods for no good reason. I, for one, have no desire to explore the wilderness and nature is just fine on tv, thank you. The environmental types are so understanding that they forget they are MEAT.
Black bears come to your house all the time. They seem to know which house has a key under the doormat. That bear seated at the picnic table expects to be fed.
Grizzlies at least assume the human they see is armed until they know otherwise. Too many grizzly rugs out there.
