““I sometimes wonder whether any of the animals I film will become extinct, leaving these images as part of the record of their time on Earth. I have filmed rarer birds than these Adelies, but when I look at the young penguins, preening and pottering about my feet, I can't help thinking it would have been like this to sit beside a group of dodos. Adelies could move further south to find more ice but eventually the Antarctic continent will block their way and that will be the beginning of the end, because penguins must always have access to the sea. Their species may become one of the earliest casualties of climate change. More young birds are coming down to the shore and as they pass I speak to each of them: 'Good luck. Good luck. Good luck.””
