Penguins inhabit one of the most secluded parts of the planet, yet human activity is threatening their existence. Warmer temperatures associated with climate change are melting the Antarctic ice faster than ever, eroding the grounds where penguins live, feed and breed, while commercial overfishing and incidents like oil spills are depleting their food supply. A 2008 World Wildlife Fund study reveals that if the global average temperatures increase by just 2 C – a distinct possibility over the next 40 years – around 50 percent of emperor penguins and 75 percent of Adelie penguins could disappear. Conservation efforts for penguins are easier said than done. Their secluded existence in the Antarctic region means there is very little data available, and manned missions are difficult, especially during the harsh winters.
