Some casinos in Atlantic City will shut off their exterior lighting and nonessential interior lighting to promote climate change awareness.

Caesars Entertainment casinos, which include Caesars, Harrah’s, Bally’s and Showboat, will join the annual World Wildlife Fund event created in 2007 as a campaign for action on climate change.

The casinos will shut off their lights from 8:30 p.m. to 9:30 p.m. Saturday and will encourage guests and employees to turn off any nonessential interior lighting for the hour.

“Earth Hour is just one of many ways that we participate in activities that improve the lives of our employees, guests and our community,” said Gwen Migita, vice president of Sustainability and Com-munity Engagement for Caesars Entertainment. “We are also encouraging em-ployees and guests to keep the spirit of Earth Hour alive by making a habit of turning off unnecessary lights and personal equipment when it is not in use, both at work or at home.”

The event has participants in 7,000 cities and 154 countries, according to the WWF.
