Leonardo DiCaprio has made a documentary about the environment and you can watch it online for free.
Before the Flood follows the actor, philanthropist and noted cargo short wearer, as he travels the globe (definitely, definitely not by private jet) discussing the Very Important Matter of global warming with governments and scientists and polar bears.
That's our synopsis, here's the official one:
"Before the Flood, directed by Fisher Stevens, captures a three-year personal journey alongside Academy Award-winning actor and U.N. Messenger of Peace Leonardo DiCaprio as he interviews individuals from every facet of society in both developing and developed nations who provide unique, impassioned and pragmatic views on what must be done today and in the future to prevent catastrophic disruption of life on our planet."
