This year's Earth Hour is just around the corner - Saturday 27th March 20:30 to 21:30 local time. I observed it last year and planning to do so this year too. Please spread the word about the event. All one needs to do is switch off all light switches and electrical appliances during this period, simple isn't it? But more importantly, all this will have a lasting impact only if we make some small changes in our lifestyle on a regular basis.You can find some interesting stuff in the official earth hour website, especially the did you know section.
