Mountain pine beetle poised to ravage Eastern Canada

Billions of mountain pine beetles from B.C. are expected to devastate forests in Ontario, Quebec and the Maritime provinces as they munch their way east over the next two decades, scientists predict in a new documentary.

"Most every scientist studying the beetle feels that it's inevitable," said David York, the filmmaker behind The Beetles Are Coming, which airs on CBC TV's The Nature of Things Thursday.

"It's going to happen and we're going to have to adapt."
