This is an interesting short film that I borrowed from People Powered (thanks Andy!), but it was originally posted by the European Christian Environmental Network. It indirectly (more bluntly towards the end) asks some serious questions about our footprint on this earth. It is in German but it does have English subtitles...the dialog moves pretty quickly but I'm a slow reader and was able to keep up. Anyhow, I highly recommend you watch it...the last minute or so is nothing short of profound...it'll probably make you think (it did me).
