Switch off your lights at 8.30 pm and support WWF's Earth Hour

"The message of Earth Hour is simple. Climate change is a concern for each of us. Solutions are within our grasp and are ready to be implemented by individuals, communities, businesses and governments around the globe.

"Earth Hour is both a warning and a beacon of hope. By switching off non-essential lights for an hour, people will join a symbolic display that can inspire the change we so urgently need.

"As we watch the lights go out from continent to continent, let us reflect on the fragility and importance of our natural heritage and pledge to protect it for a sustainable future for all."
