This is an AMAZING 5 DVD box set of the BBC's Planet Earth from 2007.  This box set was exclusively sold at the Discovery Channel Store in the early 2000s and had a 2009 release.  There are 5 disks that cover the different biomes of the earth.  They are all narrated by Sigourney Weaver and are AMAZING!  This box set has NEVER BEEN PLAYED!  IT was a gift several years ago and has sat in storage ever since.  There is some creasing to the top and side of the box because of the way it was stored, but the DVDs have never been removed from their original places.
