Leonardo DiCaprio isn't just an Oscar winning (finally!) actor, he's also a passionate spokeperson against the global issue of climate change.
His latest project is a feature documentary called Before the Flood. It's about the very real possibility of life on our planet becoming extremely difficult if we don't wake up and realise what we're doing to the Earth.
Now Before the Flood has been made available for free online, which is the kind of thing you can do when you're Leonardo DiCaprio. Watch it here.
It certainly starts with some attention grabbing imagery, and the star is joined by the likes of Barack Obama, Elon Musk, Ban Ki-Moon, Bill Clinton, John Kerry and Pope Francis during the documentary.
