> Emperor penguins can be breed in captivity, btw. So it can't be that ice is required.
You think the technology to create ice has not been invented, yet?

I probably should have said that the temperature in captivity isn't likely to be the same as that in Antarctica. I might be wrong, but I don't see them dropping the temperature to -70 degrees or whatever in captivity.
In Antarctica, they usually live on the coast, where average temperatures are around -10C to 10C, not as extreme as in the interior (-40 to -60C).
