Penguins

-Some of the challenges that the Penguins have to overcome is staying a live through the cold weather and not die of starvation.

-The way the weather is and how far away it is to get food and all the predators there around there.

-To survive brutal winters Penguins will need a lot of fur, on there body to keep them warm and they need wings to help them swim away from predators.

-There is no sunlight because thats when its winter and everything is getting cold, it effects the climate by getting cold.

-Well the ice has to be frozen solid because if not it can have cracks and break apart and it can be to cold for the eggs and die also the babies can drown since they dont know how to swim at a young age.

-It can either be to cold or to hot for the penguins to survive.
