Earth Hour: What is it?
What if everyone on Earth shut off all non-essential lights for one hour? What would the effect be?
You may remember some startling photos from last year's Earth Hour in Sydney, Australia. This photo was taken by NASA but I was unable to find the original photo. The photo here is from this website. For one hour last year on March 29, 2007, Sydney, Australia turned their lights out.
This year many more locations are joining Earth Hour and here in my household we are joining as well. Want to join in? Just go to the website and sign up. Then, on March 29, 2008 at 8 p.m. local time turn off your lights for one hour. Not sure what to do in the dark? Click here for a list of unplugged ideas.
