HOLLYWOOD actor and environmental activist Leonardo DiCaprio has been named a United Nations Messenger of Peace, a post he will use to raise awareness about climate change, U.N. Secretary-General Ban Ki-moon said Tuesday.

    DiCaprio will address a U.N. summit meeting on climate change Sept. 23, a day before the U.N. General Assembly’s annual gathering of world leaders begins. Many leaders from the 193 member states of the United Nations are expected to attend the climate session.

    “Leonardo DiCaprio is not just one of the world’s leading actors,” Ban said. “He also has made a long-standing commitment to environmental causes through his foundation.”

    In 1998, the actor established the Leonardo DiCaprio Foundation, whose mission is protecting Earth’s last wild places and build a more harmonious relationship between humanity and the natural world, the United Nations said in a statement. The organization has contributed funds toward protecting tigers in Nepal, elephants in the wild, and marine animals, including sharks.

    “I feel a moral obligation to speak out at this key moment in human history — it is a moment for action,” DiCaprio was quoted as saying in the statement. “How we respond to the climate crisis in the coming years will likely determine the fate of humanity and our planet.”
