This massive 17-DVD set is a nature-lovers treasure. These are the documentaries, Planet Earth, The Blue Planet, The Life of Mammals, and The Life of Birds, that have proven the BBC has set the gold standard for nature films and programs. The ever delightful David Attenborough hosts each of these series and every single episode features mind-blowing photography and startling facts. They are educational for sure, but also more entertainment and addictive than anything else of the sort. The set is an essential addition to the DVD collection of any nature lover or anyone with a deep interest in the “vast” world around us.
