Interesting start to Simon reeves new adventure on the bbc. Heading from Alaska down through North America to the foot of South America. Something I plan to do one day myself. Starting in Alaska he was flown north by a lady pilot who had been doing the run for 15 years, in that time the glacier she was flying over had lost 200 ft in height and had a lake on its surface aswell as exposing rocks never seen before. I guess when all the ice caps melt, the rainforests have gone, we can look back through our oxygen masks and sigh...at least we will still have 800 tv channels to watch.
