Mercy! All I can say is ... If you live in an area where you can possibly come close to POLAR BEARS ...
The least you can do is become familiar with what to do & what NOT to do in order to keep yourself from harm. Am sure the bears were there long before human beings decided to settle there, and this is *their* territory!
On a side note ...
Mr. ABC and I live in the mountains of North Georgia, and every now and then we see adult black bears (they are not all that large in size actually) wandering around on the front of our so-called lawn area. We just make sure that the gates are closed to our deck, and get on with our lives.
