Antarctica Penguins

Scientists in the Antarctic studied groups of penguins. They say that penguin populations are decreasing. Scientists found out that in some groups, the number of penguins went down by more than 75% in the last 50 years

Scientists believe that the main reason why this is happening is climate change. Ocean temperatures are going up and sea ice is melting

This is a problem for krill which is the main source of food for penguins

The situation in the Antarctic is very serious. Many animals are dying because their natural habitat is changing

This is a problem on the food chain and on penguin populations, too
