Tooth and claw: Bears

Teddy bears might be popular with children but real bears are anything but cuddly. Brown, Black and Grizzly bears are the most well-known and have a well-deserved fearsome reputation. But for most part, bear attacks are not nearly as common as you might think. They are solitary, curious and you are unlikely to see one unless you are really lucky – or unlucky depending on your point of view. So what should you do if you find yourself facing one in a forest? To learn more about these fascinating creatures, which can spend the winter months in a deep state of biological hibernation, professor Adam Hart speaks to Dr Clayton Lamb from the University of British Columbia in Canada and Dr Giulia Bombieri from the Science Museum in Trento, Italy, about their work and experiences of these amazing beasts, whose numbers are increasing in some parts of the world, leading to an increase of defensive attacks on people.
