        How the Arctic Ecosystem Might Change

        Examine the unique, yet fragile Arctic marine ecosystem, in this video segment from the National Film Board of Canada. A scientist discusses the connections that exist in the Arctic food web, whose overall lack of diversity makes many of its members prone to extinction as change occurs in their sea ice habitat. The video explains that as global warming continues and sea ice disappears from the Arctic Ocean, new species from warmer, more southern oceans will eventually replace those species unable to adapt to the changing conditions.

        This media asset was adapted from Arctic Mission: "Lords of the Arctic" by National Film Board of Canada.
