I would call for help, that's the only thing, sorry. Bears run faster than humans, and they climb faster too, not to mention I have short legs. Don't think I can outrun a bear.
Well, for one, copper forms copper oxide and copper carbonate when it's exposed to the air. That's why the Statue of Liberty has that blue-green tint to it: it's covered by copper carbonate.
