I first learned about Earth Hour last year when Marta of Postcards From the Trail participated and wrote about it on her blog. I knew I wanted to do it this year and fortunately, I got an email from the World Wildlife Fund reminding me that it's coming up this weekend.
Turn out. Take action.
Be part of this historic event.

World Wildlife Fund is asking individuals, businesses, governments and organizations around the world to turn off their lights for one hour – Earth Hour – to make a global statement of concern about climate change and to demonstrate commitment to finding solutions.
Earth Hour is a global initiative in which millions of people around the world will cast a vote in favor of action on climate change by turning off their lights for one hour on March 28, 2009 at 8:30 pm local time. By voting with their light switches, Earth Hour participants will send a powerful, visual message to their leaders...

Lots of cool info and maps on the websites. 2,848 cities, towns and municipalities in 84 countries will be participating. The lights will go off at the Great Pyramids, the Empire State Building, and the Acropolis in Athens. Venice is participating by turning off the lights on the Rialto Bridge and at La Fenice. Last year, 50 million people participated - it'll be interesting to see how many people join in this year.
From the FAQs:
Is Earth Hour merely a symbolic act?
Symbols are quite powerful. From the Boston Tea Party all the way to the sit-ins in the 60's, symbols have a way of sparking change that sweeps around the planet. Flipping the switch for Earth Hour is a way for people to get involved and demand action wherever they are. It's easy so everyone can participate no matter their location, age or income level.
What are the next steps after turning out ones lights?
Earth Hour is just the start. After the lights go out around the world we hope that conversations will continue on climate change and that people will take initiative to make small changes in their lives to be more carbon efficient. We encourage simple but effective energy-saving measures such as installing compact fluorescent light bulbs, which are more efficient and last much longer than traditional incandescent bulbs, choosing energy efficient appliances, making sure their car tires are properly inflated and unplugging electronics when they are not in use. WWF will spend the rest of the year taking the voices of the people who participated in Earth Hour to our policy makers and work with them on finding ways to get us out of the climate crisis the world is facing.
