Leonardo DiCaprio highlighted climate change risks in his acceptance speech at the Oscar ceremony last night.

Mr DiCaprio, who won the Best Actor award for ‘The Revenant’, told the audience the issues the production team faced while filming the movie due to global warming.

He said: “Making The Revenant was about man’s relationship with the natural world, a world that we collectively felt in 2015 as the hottest year in recorded history. Our production needed to move to the southern tip of this planet just to be able to find snow.

“Climate change is real, it is happening right now. It is the most urgent threat facing our entire species and we need to work collectively together and stop procrastinating.”

The actor urged the public to support leaders who “do not speak for the big polluters, the big corporations but who speak for humanity”.

He added: “For indigenous people of the world, for millions and millions of underprivileged people out there who are most affected by this, for our children’s children and for those people out there whose voices have been drowned out by the politics of greed, I thank you all for this amazing award tonight. Let us not take this planet for granted, I do not take tonight for granted.”
