Answer:

The emperor penguins live in very extreme conditions where the cold would be unbearable for most animals living on this planet, including humans. Also, they make long migrations where they spend several days without food, walking over the ice shelf and then they stoically take care of their offspring during weeks under these adverse conditions. Despite this hard way of life, the average life expectancy of emperor penguins is up to 20 years.

These weather conditions give them in return the advantage of living far from humans and other predators, keeping them away from pollution and other disturbances.

Unfortunately, Emperor penguin chicks have a high mortality rate up to 90%, during the first year of life due to predators such as giant petrels and skuas.
