More than 1,200 students from across the US assemble a five-story globe on the National Mall in Washington 21 April. The globe is part of the festivities to mark the 25th anniversary of Earth Day which will be celebrated 22 April.

This Sunday, the Earth Day Network (EDN) and Bridgestone Americas Tire Operations (BATO) will team up to present a massive Earth Day celebration at the National Mall in Washington D.C., EDN announced on the website.

“The theme of Earth Day 2012 is Mobilize the Earth, and as Bridgestone is in the business of mobilizing people, we feel this is a fitting partnership,” Kathleen Rogers, president of Earth Day Network, said on the website. “By setting clear environmental impact goals for the company and its products, Bridgestone is setting an example for the tire industry. Earth Day Network is pleased to have them on board for our flagship event on the National Mall.”

The April 22 celebration will kick off at noon and run to 7:30, featuring an assortment of local, national and international musical numbers and speakers. Its genesis can be traced back to then-Senator Gaylord Nelson of Wisconsin, who, after witnessing the catastrophe of the 1969 oil spill in Santa Barbara, California, called for an environmental teach-in, or Earth Day, to be held on April 22, 1970; over 20 million people participated that year.
