A SURVIVAL expert form Sidmouth has penned a book on how to stay alive in some of the most extreme environments on the earth.

Former Royal Marine Commando Dave Pearce is a safety advisor to the television and film industry.

His Outdoor Survival Manual outlines how to stay alive anywhere from the Sahara desert to the polar ice caps, as well as providing advice for less extreme adventures such as a family weekend in the woods.

Dave has worked with TV explorer Bruce Parry, whose new series Arctic started on the BBC this month.

The Sidmouth resident is also a regular survival and safety consultant to Bear Grylls on Born Survivor for the Discovery Channel.

Dave has climbed Mount Everest’s most challenging north face, crossed Greenland in the footsteps of Ernest Shackleton, wearing and using only the original gear and equipment of the time, and spent more than three months at a time on expeditions with no communication to the outside world.
