POLAR BEARS INTERNATIONAL

While working in the Arctic, Dr. Steven Amstrup, chief scientist of Polar Bears International, discovered something disturbing — the sea ice polar bears rely on for traveling, hunting and raising their young was disappearing. Regarded as the most influential scientist working on conservation efforts for the iconic bears and determined to create a better future for them, Amstrup and his team of international researchers provided the data needed to list the animals as a threatened species.
