Leonardo DiCaprio's foundation announced Tuesday that it will donate $15 million towards environmental causes, funding the work of groups "working to solve humankind's greatest challenge."
"The destruction of our planet continues at a pace we can no longer afford to ignore," DiCaprio said in a statement. "We have a responsibility to innovate a future where the habitability of our planet does not come at the expense of those who inhabit it."
The 40-year-old actor has been an active environmentalist throughout his career. He created the Leonardo DiCaprio Foundation in 1998, a year after "Titanic" came out, to fund efforts that protect the planet and its endangered species. It now supports such projects in more than 40 countries.
DiCaprio was recently an executive producer for the Oscar-nominated wildlife documentary "Virunga." His production company signed a multi-year deal with Netflix earlier this year to create more eco-themed films that chronicle the "urgent and important work" during this "critical time for our planet."
In September of 2014, DiCaprio addressed world leaders at the United Nations Climate Summit, urging them to address "the greatest challenge of our existence on this planet."
"As an actor, I pretend for a living. I play fictitious characters often solving fictitious problems. I believe mankind has looked at climate change in that same way," he said at the time. "My Friends, this body -- perhaps more than any other gathering in human history -- now faces this difficult, but achievable task. You can make history ... or be vilified by it."
