The Polar Bear is Growing Smaller

The polar bear grows grows smaller and smaller. Compared to its relatives from the beginning of the 1900s, the polar bear is 2-9 % smaller. The cause is connected to the increased pollution and the strong recduction of the ice cap caused by climatic changes. Cranes of the polar bear from various period have been compared. The discovery was made by scientists from Biologisk Institut and Danmark's Miljøundersøgelser (Environment Investigations).
