EARTH HOUR March 29, 2008

On SATURDAY, MARCH 29, 2008 at 8 p.m., join millions of people around the world in making a statement about climate change by turning off your lights for Earth Hour, an event created by the World Wildlife Fund.
(Our prof in atmospheric environment suggested using LED lights or crank-radio, crank-flashlight if needed, rather than, for example, candles).
