The bears can share the outdoors with people. This story is light on details but bear spray is considered the best defense against bear.
I've camped many times in bear country and slept in a tent. I kept bear spray with me at all times and fortunately had no problems...knock on wood. Most of the time it is OK but you have to be intelligent about it. Don't leave food out, carry bear spray, stay away from bear as much as possible, etc.
Also, there are plenty of great outdoor places you can go that don't have bear. Not saying they're risk free, almost nowhere is risk free. But there are "safer" parks, etc. (not "safe", just "safer").
I would never want to be only stuck inside. There's too much amazing to see outside.
