The effort that was first taken by Sydney in 2007 has now become a worldwide effort in order to spread awareness about climate change. Sydney had turned off the lights of the city and plunged in darkness in order to send messages about climate concerns to the world.
This effort was welcomed by the rest of the world as many countries participated in the Earth Hour 2009 yesterday by turning off lights for an hour. The time for the Earth Hour was from 8.30 p.m. local time in those countries.
A large number of communities in Philippines participated in this event, making Philippines the topper in Asia for its participation. The lights of the Sydney Opera House were put out in Australia. 20 Chinese cities joined the movement casting themselves in dark for an hour. Egypt, France, USA were also major participants.
Many other countries and local citizens also joined in to express their concern about climate change. The event was sponsored by the World Wildlife Fund.
