In spite of the fact that Hollywood celebrities live in fancy houses, often use private planes and galavant around the world spewing far more carbon than the Average Joe, many of them love to warn about the threat of climate change.
So it was no surprise to see many film and music stars speaking out during the recent U.N. climate summit in Paris (COP21), which was held Nov. 30, through Dec. 12.
Using their star power, these five celebs particularly advocated for radical changes such as giving up cars and plastic bags, participated in a mock trial of ExxonMobil for the “Greatest Climate Crime of the Century,” rode on a Greenpeace float and lashed out at people skeptical of the threat of climate change.
