The Arctic Food Chain

The loss of the ice caps goes far beyond the polar bears. The Arctic environment has a food chain. It all revolves around the ice algae that grows under beneath the ice. You can see it in the diagram above, it's the green stuck to the bottom of the iceberg. This algae is the main food source for copepods. Fish feed off of the copepods, and both the seals and the birds feed off of the fish. Polar bears, who are at the top of the food chain, are getting less and less seals to eat because the situation gets worse as it goes up the line. Global warming is destroying the entire Arctic lifestyle, and something has to be done to stop it.
