Some major buildings in the U.S. will be turning down the lights from 8 to 9 p.m. on March 29 to make a statement about climate change called Earth Hour. Well-known participants include the Sears Tower in Chicago, Bay Bridge in San Francisco, the Georgia Dome in Atlanta, and Phoenix City Hall in Arizona.
What is Earth Hour? It started last year in Sydney, Australia, begun by the World Wildlife Fund. Earth Hour is intended to bring together a diverse group of community, municipal, corporate and nongovernmental organizations to heighten awareness about climate change and to inspire consumers and businesses to take practical actions to reduce their own carbon footprints.
This year, Earth Hour has become a global movement. As of the time of this posting, 191,972 people and 12,263 businesses around the world have signed up to shut off their lights from 8 to 9 p.m. on March 29. Over 25 cities around the world are holding events.
