Surely they wouldn't have shot and killed any animal, would they ? I wouldn't have thought that was thier way.
The photography was just amazing and even more appreciated when you saw the diaries at the end and could see what they were up against. I must say I was very saddened by the sight of the exausted polarbear, it was brilliant watching him swim, but so very sad to see him lay down to die, it must be heart wrenching for the team to see that kind of thing.
Wasn't that bit lovely when the lady saved the penguin chick from the icy hole he was stuck in , but even more lovely when the mummy penguin waited paitently and took it back, she must have known it wasn't in any danger from the human and was being saved.
