Bear whisperer voices need for public awareness

LYME, New Hampshire - Stripy and Jake are bear cubs fed by bottle, who play around happily. Other bear orphans perch in the trees when Ben Kilham ventures into their enclosure.

Kilham lives in the woods of New Hampshire in the United States and has made it his life's work to understand black bears, winning him not just international stature but greater insight into humankind.

From the photos and paintings on the wall, to the three little wooden bears bidding visitors "welcome" at the entrance, everything in his renovated barn home exudes his passion.
