We have there critters all over the U.S in our more remote areas. Each year we have a few deaths, far more than the Wildlife Management people want to admit. Fear of being eaten cuts down on tourism and wildlife funding.
We outdoor folk do advise people to wear bells and bright orange colors when in bear territory. That way when we find bells and shreds of orange cloth in the bear poo we know why you failed to return to the trailhead.
Just imagine the result of some do-gooder throwing open the gates of the London zoo post SHTF. A predatory invasive species with no natural enemies roaming the countryside reminding the human population they are no longer the top of the food chain.
