It is about time nature intervenes to put man in check for killing magnificent animals like Tantiana. The reason that the Siberian Tiger was able to escape was due to incompetent and neglient zoo personnel. The San Francisco Zoo and others should stop removing these animals from their natural habitat for the amusement of vacuous humans. If humans want to make a positive contribution, efforts should go to preserving all species in the wild. The planet is in desperate need of cataclysmatic event to eliminate humans from earth to save other life forms. I would love to see the time when animals have dominance over humans.
