North America faces beetle plague

A plague of tree-killing beetles which swept across British Columbia is threatening to spread to the US.

The mountain pine beetle has killed more than half of all lodge pole pine in the province and is now active in neighbouring Alberta.

Cold winters usually kill off the beetle larvae, but the region has been warmer than usual in recent years.

Scientists say the beetle could attack and kill jack pines, which are found throughout North America.
