The city of Niagara Falls is encouraging residents to take part in Earth Hour on March 24, by turning off all their lights from 8:30 p.m. to 9:30 p.m.

The Earth Hour movement started in 2007 in Sydney, Australia and saw more than 2.2 million individuals and 2,000 businesses turn off their lights for one hour to take a stand against climate change. 

By 2008, Earth Hour had become a global movement with more than 50 million people across 35 countries and territories participating.

Global landmarks including Niagara Falls and the CN Tower in Toronto have been turned off in previous years for Earth Hour.
