Caribou in Athabasca oil sands threatened by human presence

The caribou population in the Athabasca Oil Sands area in Alberta, Canada could be extinct in 30 years due to human activity, according to new research.

Wolves have been blamed for the dwindling caribou population in parts of Alberta, but research published in the June issue of Frontiers in Ecology and the Environment says human activity related to oil production and the timber industry could be more important than wolves in the caribou population decline.
