<P> In November 2010, DiCaprio donated $1 million to the Wildlife Conservation Society at Russia's tiger summit . DiCaprio's persistence in reaching the event after encountering two plane delays caused then Prime Minister Vladimir Putin to describe him as a "muzhik" or "real man". In 2011, DiCaprio joined the Animal Legal Defense Fund's campaign to free Tony, a tiger who has spent the last decade at the Tiger Truck Stop in Grosse Tête, Louisiana . </P> <P> In early 2016, at a meeting with Pope Francis, he gave a charity donation and spoke about environmental issues . A few days later, possibly influenced by his meeting with DiCaprio, the Pope said he would act in a planned faith - based charity film, Beyond the Sun . It would be his first acting experience, and would also be the first time in history that a Pope appeared in a feature film . Profits from the film would be given to charities in Argentina . </P> <P> In October 2016, DiCaprio joined forces with Mark Ruffalo in North Dakota in support of the Standing Rock tribe's opposition to the Dakota Access Pipeline . </P> <P> In April 2017, he promoted and protested President Trump's inaction on climate change by attending the 2017 People's Climate March . Leonardo DiCaprio is identified as one of the most active celebrities in the climate change movement . Not only did he highlight the topic at the Oscars but he is a constant source of information on the matter . Many political figures welcome high - profile influencers such as actors as Leonardo DiCaprio or artists to address political causes, environmental or not, "because of the high recognition that celebrities have", states Eric T. Kasper, an associate professor of political science . He claims that much of the public feel a personal connection to the stars after experiencing emotion from them in so many different ways on the big screens . While budgets in the science and technology sector are declining as well as interest in newspapers and scientific journal series, it is important to have more familiar faces and voices such of those from celebrities to represent the importance of subjects such as climate change . </P>
