In Norway we recently had a case where an American journalist was missing for nearly a week in rough terrain with bad weather on top of that. However, he was found alive, despite having some serious injuries, because he had equipment and warm clothes to keep him alive.
Not everyone is so lucky. And it's getting worse; people come to the mountains and the such thinking that all they need for their hikes to Instagram-worthy spots are a t-shirt, shorts, and flip-flops. Forget about the backpack with at least a change of clothes and some food and water; that ruins the outfit. Rescue operations are costly, and those doing the rescues also risk their own lives to save the lives of people who never should have been out in the first place.
I know Norway isn't the only place this happens. But how bad is it where you are?
