sea otters
Sea otters are small mammals. Recently the sea otters off the coast of Alaska started to decline. Two reasons pointed out as the source of the decline. One was environmental pollutants and the other was large predators.
First, one reason pollution was believed to be the main source of sea otters declined is the fact of the well-know oil rigs along the Alaskan coast. Also water samples of the Alaskan coast have shown increasing numbers of chemicals that might have affected the immune system of the sea otter population.
Another reason was pollution is believed to be the culprit of the decline of sea otter population is the disappearing of other sea mammals along the west coast of Alaska, such seals. Environmental problems affect an entire ecosystem, not only a single species. Only large predators like orca ( large predator whale) can cause the same effect of an environment.
