Mark your calendars!
Saturday, March 28th, from 8:30-9:30 in the evening, be sure to turn off all of your lights and televisions and other electronics.
But WHAT TIME ZONE!?!?!
Simple answer- all the time zones are sharing the exact same time! So it's very easy to remember. 8:30, no matter where you are.
There are some interesting stats from last year here.
This is also a neat video about Earth Hour starting in 2007:
The video is less than 3 minutes and fascinating! Be sure to check it out.
What else can you do...? Spread the word!
Send an email about this event to all of your friends and family and encourage them to pass it on. You can even print and post posters/flyers from the official website, but just try not to be wasteful about it- and of course, use recycled paper! :)
