Bears are well known for their sensative noses. Polar bears are reputed to be able to smell an injured seal up to twenty miles away. Here, on Cape Churchill, the bears are attracted to the smells of the food brought with them by the tourists. This photo is of "camp," a place where the tundra vehicles often stop while the visitors are having lunch. Attracted by the tasty smells from inside, the bears wait and watch, hopefull for a scrap. They are not so lucky. It is for their benefit, rules on the behaviour of tourists have been enforced in the area to protect them from human kindness. Bears who learn to eat human foods quickly become dangerous and must be destroyed.
