Tomorrow at 8:30 p.m. local time, millions of people around the world will come together for climate change and turn off their lights for one hour. Since it began three years ago, Earth Hour has become a global phenomenon, with participants from New Zealand to Hawaii. Last year, nearly one billion people participated, including 4,100 cities in 87 countries on seven continents. Eighty million of those were Americans, and some of our most iconic landmarks, like the Empire State Building, the Golden Gate Bridge, and the Las Vegas Strip, took part.
So, hit the lights tomorrow! It really couldn't be easier, and I'm sure you can think of a few things you can do in the dark. If you need illumination, try some pretty, eco-friendly candles — lighting candles is A-OK!
Take a look at some images of international landmarks last year during Earth Hour comparing the moments before and after they hit the switch:
