Leonardo DiCaprio's National Geographic climate change documentary, Before the Flood, is available to watch in full for free on YouTube.

The documentary, which features a soundtrack by Mogwai and Nine Inch Nails' Trent Reznor, sees the Academy Award-winning actor travel around the world to visit the places where the effects of global warming are felt the most. The Titanic, Wolf Of Wall Street and The Revenant star heads to rainforests, glaciers and reefs, and along the way gives an address at a U.N. climate change summit, and meets the like of Pope Francis, Barack Obama, and Elon Musk.

“Climate change is the most critical and urgent problem facing our world today, and it must be a top issue for voters this Election Day,” DiCaprio told The Hollywood Reporter. “Fisher and I set out to make a film that not only educates people about the challenges we face if we fail to act, but one which also shows the solutions we can implement if we can find the political will to do so. We need leaders not only in the United States, but across the globe, who believe in the science of climate change and who have the courage to take a stand for our planet.”

All in the name of raising awareness for what we’re doing to our planet ahead of the election, Before the Flood is directed by Fisher Stevens, who won the Documentary Feature Oscar for The Cove, and penned by writer Mark Monroe. It's unclear whether National Geographic will leave the documentary on YouTube permanently, so watch it above now while you still can.
