A mesmerizing journey through mountains, oceans, jungles, deserts, well, through the whole world, really. In the first episode we get to see the dramatic life of a compressor diver and how Pa-aling fishermen live.The whole thing has 7 episodes, each containing around 60 minutes- totally worth the time. In fact it would be a waste of time not to see this. Five stars, no debate. Hat's off to BBC for making this happen.
