What global event transpired last Saturday night? Are you even aware that there was a significant global event that was supposed to take place from 8:30 to 9:30? Shame on you if you didn’t know it was Earth Hour! But even if you didn’t know and you didn’t participate, the said even was still a huge success according to environmental activists. The participation of over 88 countries in the world was greatly felt as time zone by time zone, the lights dimmed from 8:30-9:30. Over 4,000 cities and towns turned off their lights for a full hour to help raise awareness about the threat of climate change, particularly global warming.

This year is actually the third consecutive year for the Earth Hour. It began in 2007 in Australia. Only few participated then, but last year the participants expanded to over 400 cities worldwide. And it grew even bigger this year.

Earth Hour executive director Andy Riley says, the Earth Hour is an idea of hope and not of despair.

I think Earth Hour is a great way for everyone to pitch in so as to save our planet. It’s not such a big sacrifice to turn off the lights for an hour, right?

So, if you didn’t do your part this year, it’s not yet too late. 2010 Earth Hour won’t be far along!
