Antarctica:
Adélie Penguins

The Adélie penguin is the smallest and most widespread penguin species in the Antarctic. While the Adélie penguin population are steadily rising, in areas of the Antarctic more affected by climate change, their numbers have fallen by more than 65% in the last 25 years! That is way too much. Adélie penguins are extremely important to the Antarctic food chain. They eat the krill and small fish,and the warming climate is making it harder and harder for them to survive.
