    Penguins Disappearing in Western Antarctica

    Numbers of penguin species are declining in western Antarctica, according to reports. The decline has been attributed to a fall in the availability of krill, a shrimp-like creature that usually provides the biggest source of food to the flightless birds. The reduction in krill numbers is due to a rise in water temperatures, a decline in ice cover and more whales and seals. The region is one of the fastest-warming on the planet, with 5 or 6 degrees Celsius rises in air temperatures in winter. Researchers have claimed that if temperatures continue to rise, then krill will become more scarce, and consequently numbers of penguins will continue to fall.
