Releasing films online and in streaming before theatrical releases - or even circumventing traditional media for films - is fast becoming the norm for documentaries.

Making A Murderer, Amanda Knox and countless other documentaries have all been uploaded to Netflix without so much as a whisper of a cinema or broadcast television release because why bother? If you've got a platform and you want everyone to see it, why force people to watch it when you want them to?

Leonardo DiCaprio's latest documentary, Before The Flood, explores the topic of climate change and his own campaign to combat and prevent irreversible damage to our wildlife and natural resources. The feature-length documentary, which was produced in conjunction with National Geographic, was made available on YouTube today.

For free. No charges. No ads. No nothing. All of it.

Here it is. Get a cup of tea and sit yourself down because this really is worth your time.
