Penguins

Animals that live in the coldest parts of the world depend on ice for protection and a home. With the temperatures warming it is making the penguins more vulnerable and much easier for prey to get because the ice is getting thinner. You also have to think that penguins need to cross the ice to get to the breeding grounds and thats not easy if they are falling into the water and getting eaten.

What you probably don't know is that penguins have to worry about sunburns. They live in places where are reasonably cool. They have to hide there feet so they don't get burnt and for baby penguins it is even more dangerous. When baby penguins are born they don't have any feathers so there skin is more vulnerable from the sun rays. The penguins are then forced to go into the water to cool off making it very easy for predators to get them.
