From its debut in one city in one country, viz. Sydney, Australia when 2.2 million individuals turned off their lights to take a stand against climate change, Earth Hour has become truly global, embracing 128 countries and territories in 2010.

This Saturday March 26, for Earth Hour, people throughout Australia, some parts of Indonesia, and around the world will switch off their lights to show their support for action on climate change and sustainability.

If you’re doing something special for this event, share your story.

Can your CAS community make a difference and go beyond the hour in 2011?
