I really enjoyed this BBC video about elephants thriving in Botswana. I learned about two interesting things - this wonderful organization EWB, and the existence of political refugee elephants!
EWB is gathering a lot of information and learning more and more about these majestic creatures. See this Animal Planet video that suggests that elephants have very complex intellectual processes. Founder Dr.Mike Chase has a doctorate in Elephant Ecology and loves these giants with a passion.
