Earth Hour is the single, largest, symbolic mass participation event in the world. Born out of a hope that we could mobilize people to take action on climate change, Earth Hour now inspires a global community of millions of people in 7,001 cities and towns across 152 countries and territories to switch lights off for an hour as a massive show of concern for the environment.
