"The World Wildlife Fund's now annual Earth Hour campaign is great way for individuals to take a stand against climate change. Something as simple as switching your lights off for one hour can make a visual statement of your support for the global sustainability movement. \nBegun back in Australia in 2007, last year's event saw such world famous landmarks as the CN Tower in Toronto, the Golden Gate Bridge in San Francisco, Rome's Colosseum, and The Eiffel Tower flick the switch on their illumination, not to mention the millions of people across the world who did the same on a smaller, but no less important scale. \nEarth Hour 2010 takes place today, Saturday, March 27th at 8:30 p.m. your local time. As well as turning your lights off for the allotted time, here are some other social ways you can show your support for Earth Hour.\n1. On Twitter\n\n\n\n\nA global \"lights off\" event is planned for everyone's favorite micro-blogging service Twitter with a click-through app you can activate now that will automatically turn the lights off on your Twitter profile picture for Earth Hour. The app auto-tweets out a get prepared message to your followers as you activate it, and will do the same when the hour begins. You can also add an Earth Hour \"Twibbon\" to your Twitter avatar. \n2. On Facebook \n\n\n\n\nJust like the Twitter lights off option, there's one available for Facebook too created by Fennek &amp; Friends. As with the previously mentioned version, this one-click app will turn the lights off your profile picture at the correct time. Another Facebook option is an app that installs a virtual light switch \u2014 one that's customizable, as well as shareable \u2014 which can be found via the \"light switch\" tab on Earth Hour's Facebook Fan Page.\n3. On Your Website\n\n\n\n\nYou can create and embed a virtual lantern on your website with some simple HTML code, available to copy and paste here. There's another embeddable widget from Call2Action that can also be posted on your website or blog, or can be e-mailed or shared via the usual social networking channels. \n4. On Flickr\n\n\n\n\nThere's a dedicated Earth Hour account on the photo sharing service Flickr that will show pictures of various lights out ceremonies. Don't forget to subscribe now and check back for some great shots when the lights come back up. Tagging your own relevant pics \"earth hour\" on the site will add them to the pool.\n5. On YouTube\n\n\n\n\nThere's a great Earth Hour YouTube channel that offers some amazing clips from years past.  They include both overview videos about the movement, and footage from individual events around the globe. Subscribe, watch, and be inspired to get involved and spread the word!\n\n\nFor more social media coverage, follow Mashable Social Media on Twitter or become a fan on Facebook\n\n\nMore social media resources from Mashable:\n\n- 6 Easy Ways to Score the Best Deals with Social Media- How the Fashion Industry Uses Location-Based Marketing- How Companies Are Using Your Social Media Data- How Twitter in the Classroom is Boosting Student Engagement- How Musicians Are Using Social Media to Connect with Fans"^^<http://www.w3.org/2001/XMLSchema#string>
