1 Hour: Lights Off

Help save our planet. Join the Earth Hour 2008 Campaign. Millions of people across the world will be participating in Earth Hour... tonight. Find out more about the campaign here.

But the gist of it is this: At 8pm tonight (in your own time zone) turn your lights out for 1 hour. Simple enough. And it will save tons and tons of electricity.

"Earth Hour shows that, together, our small actions can make a difference to global warming."
