Saturday night, March 28, the UT Tower will go black in recognition of Earth Hour -- a global event that raises awareness about humanity's collective impact on the planet and how we can make a positive difference towards its preservation.
Only the clock faces and aircraft warning lights will remain illuminated.
This marks the sixth year that UT has participated in Earth Hour. Those wishing to participate more fully at work or at home are encouraged to turn off all nonessential lights to raise support for energy conservation.
Earth Hour was conceived in 2007 as a simple way to engage people in the issue of climate change. It has since expanded into a global phenomena that includes hundreds of millions of people. Organized by the World Wide Fund for Nature, the movement emphasizes the need for climate change awareness to extend beyond the day of the event and into the daily concerns of individuals and communities.
