It began in Sydney, Australia in 2007, when 2.2 million homes and businesses turned off their lights for one hour. It has since grown to more than 4,000 cities in 88 countries.The effort is organized by the World Wildlife Fund (WWF). The local WWF Earth Hour ambassador is Audrey le Goff, who contacted St. Catharines businesses to encourage them to participate in Earth Hour. She also distributed tool kits at St. Catharines malls containing posters, fundraising tips and other information, she said.“Climate change is the biggest environmental threat to our planet and the No. 1 concern for Canadians,” she said. “Participating in Earth Hour is a very simple way to show that you want to be a part of the solution.” read more
