Canada's Declining Caribou Population

Canadian Geographic posted this map as a snapshot of the status of caribou herds.

This map, while visually appealing is a little hard to grasp. The colors represent groupings (referred to as "designated units") of caribou species and the text around the map is color coded to these groups.  The circles show the highest estimated population in gray versus today's estimated population, color coded to the designated unit.

In the words of Justina Ray, the president and senior scientist of Wildlife Conservation Society Canada

“We are a natural resource-driven economy, and limits to our footprint is anathema to most. Our system of monetizing does not extend to species. They have no value.”
