Why don't emperor penguins just breed by the sea?

Question

I say March of The Penguins, and I'm wondering...why do emperor penguins take that trip? From the information for the movie there's no reason. If they all stayed by the sea they wouldn't have to exhaust themselves through travel, they would have a supply of food which would save many penguin lives, their babies would also have more food saving their lives. The only thing I don't know about is the weather. I mean, why march to a desolate place in the middle of the arctic with no food where you can starve or die of cold when you could just stay put and eat fish?

Answer 1

LOL I havent seen the movie yet but loved the question,yeah why?

Answer 2

Did you notice in the movie how there are virtually no predators in the middle of Antarctica?  That's why.

It's like why people choose to live in the suburbs and commute vs. an inner city apartment close to work.
