Canadians go dark with world for Earth Hour

Canadians joined communities around the world on Saturday in turning off the lights for this year's Earth Hour, a global campaign to raise awareness of climate change. About 100,000 Canadians out of a total of 300,000 people worldwide registered online for the event — putting the country among top participants anywhere.

Organizers see the event as a way to encourage the world to conserve energy. While all lights in participating cities are unlikely to be cut, it is the symbolic darkening of monuments, businesses and individual homes they are most eagerly anticipating. (CBC)
