Sea ice around the Antarctic's Deception Island. "Actually, in the 90's it was thought that the climate change would favor the chinstrap penguin, because this species prefers sea waters without ice unlike the Adelie penguin which prefers the ice pack," study researcher Andres Barbosa told LiveScience. The sea-ice decline in the winter, however, has become so big that it is now impacting krill populations, said Barbosa, of the National Museum of Natural Sciences in Madrid.

But Barbosa says the chinstraps aren't a lost cause. "This is an example of how the human activity far from the poles can affect the live at thousands of kilometers far from our homes," Barbosa told LiveScience. "Therefore, a more responsible use of the energy and the fossil fuels is necessary to preserve the planet and then the Antarctica."
In addition, he said, to protect the organisms that call the Antarctic home we need to reduce human impact by reducing overfishing, tourism and even research activity.
