i didnt get to see planet earth, but im making it a point to see every epsiode of life. one thing that always breaks my heart is when i see animals die because of our encroachment into their environment. (ie dead white tail deer hit by cars on the side of the street because we really needed to pave over their land for another strip mall or housing plan. ) and if im crazy for being moved by the story of the octopus, then so be it. also the poison dart frog will hatch its tadpolls in a small pond, and then in the dry season move them to different sitting pools of water in trees and plants, sometimes climbing over four miles into the trees. then she will travel to each location daily to feed the tadpolls an unfertilized egg since there isnt enough food in the small pool.
