Why Leo DiCaprio Was Never The Same After The Revenant

So what was DiCaprio up to during those years when he wasn't acting? Well, he was devoting most of his time to activism. Ever since his early 20s, DiCaprio has been interested in using his platform to advocate for sustainability and raise public awareness about climate change. In 1998, he met with former vice president Al Gore to discuss protecting endangered species, and he began donating millions to the cause. But what was it about shooting The Revenant that made him even more motivated when it comes to environmentalism?

While filming, the cast and crew was essentially forced to witness the effects of climate change up close. They had originally planned to shoot in Canada, but they had to switch to Argentina instead because there simply wasn't enough snow up north. At the time, 2015 was the hottest year in global history (now, 2016 holds the top spot). "We are actually seeing the tipping point happen right now," DiCaprio told The Telegraph. It was one thing to hear about global warming, but seeing it in person made him confront the dire situation head-on.
