History of Earth Hour in United States and How to Celebrate/ Observe It

Earth Hour is an event that started in Australia in 2007 as a way to raise awareness about climate change and the need for sustainable living. The event is held annually on the last Saturday of March, and participants are asked to turn off all non-essential lights for one hour, from 8:30 to 9:30 pm. In the United States, Earth Hour is organized by the World Wildlife Fund (WWF), and many cities and landmarks participate by dimming their lights. Some of the most recognizable buildings and sites that have gone dark for Earth Hour include the Empire State Building, the Golden Gate Bridge, and the Las Vegas Strip.
