How to scare off a polar bear

CNN has posted a short list of survival tips from Pen Hadow.

Hadow is "a veteran polar explorer and Arctic expert. He was the first person to trek solo and without resupply from Canada to the North Geographic Pole and was part of the first Catlin Arctic Survey with two colleagues," according to the post.

My personal favourite is tips on how to avoid a polar bear attack.

"Their eyesight isn't great, so your best move is to deploy bear bangers -- bright, loud flares -- and activate a shrill personal attack alarm that should frighten your local visitor away. Having a dog is a real help. They can tell if there are bears nearby much sooner than a human, and their barking is often enough to put off a bear."
