Before the Flood

Leonardo DiCaprio has long been an advocate for environmental conciseness, and his documentary film 'Before the Flood' does an excellent job to explain the threats climate change pose to the world.

Throughout the film, the Hollywood star meets with scientists, activists and world leaders to discuss the challenging position humanity has put the Earth in, and what the implications of those actions are.

Looking at the finished documentary, DiCaprio said: "People always talk about climate change in the distant future, this intangible thing that we can’t control. But it’s happening right now, you know? It’s happening — to go to the Arctic and see that these ice shelves are disappearing, that Greenland is melting decades ahead of scientific predictions. That’s the terrifying stuff, truly. Climate refugees, freak hurricanes and storms that are going to continue - wildfires, droughts. That is terrifying, and I continue to be terrified about the future, really."
