Words are powerful, especially when they come from influential people. When people in positions of power speak, the public listens that much closer to what they have to say and pay more attention to the subject that they’re talking about. For years, Leonardo Di Caprio, a famous Hollywood actor, was one of the sole celebrities who used his popularity to bring attention to climate change and other environmental issues. Using his status to draw attention to this crucial subject matter spurred on more and more people engaging with the subject and supporting efforts to fight back against global warming. Here are just a few of those influential people and what they had to say on the matter.
