The Hollywood actor Leonardo DiCaprio in 1998, after his success with Titanic, decided to found the Leonardo DiCaprio Foundation, a non-profit organization dedicated to promoting environmental awareness. Although the foundation is dedicated to all areas of the environment, it is mainly focused on global warming, supporting renewable energy and preserving the biodiversity of the Earth. In 1999 he dedicated himself to documentaries made in South America on the emergencies of the Earth and opened a website dedicated to endangered animals and the environment. In 2010, he donated $1 million to WWF to save endangered tigers and preserve their habitat, and another $1 million to Haiti following the earthquake. In 2013, it donated 3 million to protect 3200 Nepalese tigers.
In July 2014, he organized a fundraiser in Saint-Tropez in which both he and other celebrities auctioned off personal items: he managed to raise $25 million used to protect oceans, forests, nature reserves and endangered species. In July 2016, his foundation allocated $15.6 million to help protect wildlife and the rights of Native Americans, along with the fight against climate change.
In 2014 he was appointed Messenger of Peace by United Nations Secretary General Ban Ki-moon, while in 2016 he was placed by Time magazine in first place among the 100 most influential people on the planet, in the iconic category.
