Leonardo DiCaprio continues to be a passionate advocate for action on climate change.

'The Revenant' star stopped by The Ellen DeGeneres Show on Friday to discuss his new documentary, Before the Flood, and offer an impassioned plea for voters to keep environmental issues at the forefront of their minds when they head to the polls on Nov. 8.

"This is happening faster than anyone could have predicted, it's a very urgent issue," the 41-year-old actor argued. "2016 was the hottest year in reported history, July was the hottest month in reported history, and we want people to keep that in mind when they go to the polls."

"We need leaders that want to take action on this issue; that believe in modern science," he added. "Go out there Nov. 8, please vote."

The Oscar winner's friend, Kate Hudson, raved about the program on Instagram on Friday, writing, "My friend @leonardodicaprio has done an amazing job on this doc and it's a must must see!!! Watch with your family! Inform your kids! We must all be apart of saving our beautiful planet and it begins with educating ourselves."

"I like to keep my private life as private as possible, but if I'm going to be the person that's the narrator of this film, I wanted to take center stage as somebody who asks questions in a way that people would be able to digest it better," he explained.

"I think the media has improperly represented the fact that there still is an argument going on," DiCaprio added. "You have 97 percent of the scientific community saying that man is contributing to this issue and we have the ability to turn this all around."
