Professor Dee Boersma, working with the Wildlife Conservation Society and the Province of Chubut, has been studying the Magellanic Penguins of Argentina. "In 1983, we realized that oil pollution was really a huge problem for these birds. We were seeing birds coming ashore, covered in oil. We started bringing this to the government's attention. And in 1997, they moved the tanker lanes further offshore. Some years we get no penguins dead on the beach covered in oil." To learn more visit the Center for Ecosystem Sentinels website.
