Magellenic penguins, the kind that live in southern Argentina and on the Malvinas Islands, are declining in number due to climate change and over-fishing.According to the New York Times, this trend has been observed by scientists over the last 30 years.Breeding pairs are down 22 percent and the birds must swim 40 extra miles a day to find their sources of food.The scientists are blaming over-fishing as well as global warming for these problems and argue that the deteriorating condition of penguins is a sign of trouble for the whole marine ecosystem.These penguins are popular with tourists in Southern Argentina, as are the whales that swim up the coast past the Valdez Peninsula.Protecting them is important but difficult, and affirming their importance through tourism is one of the many ways Argentines and foreigners cope with the problem.
