Earth Hour

World Wildlife Fund is sponsoring Earth Hour around the world. According to a press release:

With less than a week to go, participation in Earth Hour has grown dramatically as nearly 200 cities, including 35 in the U.S., join millions of individuals and businesses around the world in turning off their lights on Saturday, March 29th from 8 – 9 pm local time in a dramatic symbolic gesture in support for action on climate change.

Christian Science Monitor reports plans in Chicago:

Guests at the Inn of Chicago on the city's Magnificent Mile will walk into a darkened, candle-lit lobby. And when they look out at the iconic skyline, it will look different: the Sears Tower, the Hancock Building, the Ferris wheel on Navy Pier, and some 200 downtown buildings plan to turn out the lights at 8 p.m.

It's all part of "Earth Hour," an international climate-change awareness campaign that started last year in Sydney, Australia and that the World Wildlife Fund (WWF) is taking global this year. Starting in New Zealand, and rolling out through dozens of cities, including Bangkok, Thailand; Dublin, Ireland; and Tel Aviv; the campaign is urging individuals, businesses, and landmarks to go dark between 8 p.m. and 9 p.m.
