The polar region -- which includes the Arctic Ocean and parts of Alaska,
Canada, Denmark, Finland, Russia, Norway and Sweden -- has experienced
unpredictable climatic changes over the last few years. As a result, polar
bears and their natural habitat are seriously threatened.
"The climate changes seem to be caused partly by natural factors about which
we can do nothing, such as anomalous solar activity," said Vyacheslav V.
Pankov, director for the Guild of Russian Ecologists. The guild was created to
unite Russian ecologists and experts on the environment.
"But the environmental effects of human activities -- pollution, destruction of
natural migration routes, a reduction of food sources -- create additional
problems for the conservation of biodiversity," he added.
