We didn't really need another reason to love Leonardo DiCaprio, but he just gave us one!

The philanthropic Wolf of Wall Street star just pledged $7 million to marine conservation efforts to help protect the world's oceans.

Speaking at a State Department conference in Washington, D.C., Tuesday morning, the Oscar nominee urged global leaders to also take action.

"This isn't simply an exercise in wildlife conservation," the 39-year-old said. "If we don't do something to save the ocean now, it won't be just the sharks and the dolphins that suffer. It will be our children and our grandchildren."
