CANADA - AUGUST 27:  The wild animals featured in "The Last trapper" a film by Nicolas Vanier - Two young grizzlies gambol in the water at Groose Mountain in the province of British Columbia - The sheer size and weight of the bears is tremendous - When one growls at you, even if it is a cub, do not lose your calm and wait until the bluster is over - Unlike the polar bear, grizzlies do not generally attack people - No more than a dozen cases a year are reported - They will defend themselves or their young ones if a human gets too near, but generally they flee human presence - Like most wild animals they do not like man in British Columbia, Canada on August 27, 2004  (Photo by Eric TRAVERS/Gamma-Rapho via Getty Images)
