Tonight, at 8:30 in whatever time zone they live, millions of people will be turning out their lights in a symbolic action pressing for worldwide change on energy and our relations with the More Then Human World.

Sponsored by the World Wildlife Fund, the Earth Hour website reports

Earth Hour organizers have commitments from nearly 300 U.S. cities and
towns, with some of the nation’s most famous skylines darkening on
Saturday night, including Atlanta, Baltimore, Boston, Chicago, Dallas,
Houston, Las Vegas, Los Angeles, Miami, Nashville, New York, Salt Lake
City, St. Louis, Tucson and Washington, D.C. In each of these cities,
individuals, businesses and organizations are participating in
activities to engage, enlighten and spread the message that together,
each one of us can make a difference on this global issue. Flagship
states include Arkansas, California, New Mexico and Pennsylvania.

The actual photographs of major cities in Australia turning dark is amazing, and a sign of hope for us all.  My lights will go out and I hope yours will also.
