Leonardo DiCaprio speaks onstage during the 2019 Global Citizen Festival: Power The Movement in Central Park on September 28, 2019 in New York City.

He criticized world leaders and corporations for their unwillingness to address climate change, and called for fundamental change.

“Our future is being gambled away, and our leaders, those whom we entrust to protect us and set the example, are either failing to stop these dangerous trends or, in some cases, denying the very science of this climate catastrophe.”

“Some have reacted to this movement with insulting tweets and negative talking points, individuals that seem to care more about their own self-interests than about your future, but we know that the climate youth movement is more important than at any time in human history.”
