Filmmaker Louie Schwartzberg has been creating thoughtful works of art using time-lapse photography for the past 30 years. Watching flowers open towards the sun or clouds rush across an azure sky underpins the fragility and beauty of our earth. "We protect what we fall in love with," says Schwartzberg: a convincing argument for everyone to get involved in solving climate change. His latest video, narrated by Morgan Freeman and scored by Hans Zimmerman, was shown at Climate Summit 2014. Watch the video and you will realise that, as Freeman says, changes are not only possible but what the future requires of us. takepart.com/video/2014/09/17/whats-possible-un-climate-summit-opening-film
