Leonardo DiCaprio recently narrated a documentary 'Carbon' that focused on climate change and the impact of carbon emissions.

In the 8-minute environmental project, the 39-year-old actor said that humans, who were responsible for the climate change, should put "a price on carbon" now so that the fossil fuel industry won't be able to make billions at their collective expense, Us Magazine reported.

'The Wolf of Wall Street' star will also be narrating three other upcoming short documentaries focused on climate change, 'Green World Rising', 'Restoration', and 'Last Hours'.
