Just as responsible travel contributes to conservation goals, events such as Earth Hour unite communities around the world for the greater good.
On Saturday, March 23, turn out the lights for one hour starting at 8:30 p.m. Show your solidarity with millions of others to bring the focus back to what matters--this planet--your global community.
Take a look at what some of your favorite cities in the United States are doing to prepare and adapt to climate change.
