Telling us a story about the connection between one's dreams and one's purpose and the powerful experience of being in touch with nature beyond the filters of civilization.
I recommend to watch this TED talk with the UN sponsored documentary Before the Flood.
Leonardo Di Caprio visits different locations on our planet that clearly show to which level our species the degradation of nature has already driven. A powerful mind changer, which hopefully does also change the action of its audience.
Its truly sad and idiotic that a full length copy of Before the Flood was removed from Vimeo due to copyright infringement. Why would someone put business interests over creating awareness for the precarious situation of our planet?
