The historic El Capitan theatre in the heart of the Hollywood section of Los Angeles is one of a number of iconic Los Angeles venues that has agreed to turn off exterior lights from 8.30 p.m. to 9.30 p.m. tomorrow as part of Earth Hour.
Earth Hour, a global initiative organised by the World Wildlife Fund, is asking individuals, businesses and governments around the world to turn off their lights for one hour - Earth Hour - to make a global statement of concern about climate change.
