Jeez I don't know where to start with the opening episode, so many highlights.
The fighting polar bear, who by the end looked as though he'd done 12 rounds with Tyson!
The 18 million (yes that's right) shearwaters going fishing alongside the humpbacks
The stunning colour of the lakes in Greenland
The icewalls exploding in the glaziers which then develop into icebergs, and the shapes of some of those icebergs are amazing.
The surfing penguins so cool
The team work by those bloody terrible orca's as they hunted the weddall seal poor thing
Seeing the life underneath the frozen water, ice-fish, which apparantly have anti-freeze inside their bodies, say nothing of the sea spiders and what looked like woodlice.
The caves under the ice block, with crystals as big as men!
Also when you see the vastness of the south pole it makes you admire the likes of Scott even more, I mean without all the vehicles we take for granted now, how did they manage it back then.
Also the mountain that had been eroded into almost nothing by the elements, the winds in the south pole blow at about 200 miles an hour. The sculptures that have been created by the winds there, looked at if they belonged on a Hollywood film set.
The whole thing was just amazing, if you haven't already seen it, get onto iplayer you won't regret it. Can't wait for episode 2 now.
