The actor's foundation announced today it has awarded USD 15 million in grants to a host of environmental organizations, including Amazon Watch, Save the Elephants, Tree People and the World Wildlife Fund.
"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 groups receiving the grants are "working to solve humankind's greatest challenge," he said.
Last year, the United Nations named DiCaprio a UN Messenger of Peace with a special focus on climate change.
