BBC documentary series

There were three BBC documentary series I've watched recently:

• Yellowstone (IMDB, Wiki)
  a 2009 documentary about my favorite national park I can think of. This three part series shows us what goes on in Yellowstone throughout the year. Each part is about different part of the year and shows ups and downs of commodity of living in this beautiful piece of Earth. It only encoureges me to go there by myself someday.
  
  
• Earth: The Power of the Planet (BBC, IMDB, University of Plymouth)
  a 2007 documentary series where in five episodes geologist Iain Steward takes us around the world to show us all the nature wonders and beauties our planet has to show. It also shows us how very small we are and what some real powers of our planet are. Also he shows us how human race is changing the planet and what are the consequences of our doing. At the end he faces us with the fact, that it is not planet that might "die" if we don't start taking better care of it, it is us that won't be able to survive in conditions that we are creating.
  
  
• Planet Earth (BBC, IMDB, Wiki)
  a 2006 documentary series in eleven parts. If I would have known sooner that the US version was nerrated by Sigourney Weaver I would have watched that one. But anyway. It is a series that shows us nature in all of its beauty. The places of the earth one could never see by himself, spices of plants and animals I've never heard of before. It was well worth watching to see what all our planet hold and what all there is to see in the nature.

All the documentaries are awesome and if you haven't seen them yet, you should watch them as soon as possible.
