On the 25th anniversary of the Chernobyl nuclear disaster, Greenpeace activists deploy a banner inside Grand Central Station to highlight the threat to millions of people from New York's Indian Point nuclear plant. 17 million people live within 50 miles of Indian Point, an old nuclear plant in an active seismic zone just north of New York City. If an accident or terrorist attack led to a catastrophic release of radiation, evacuation would be impossible. Nationwide, 1 in 3 Americans live within 50 miles of a nuclear plant. Greenpeace is calling for the shut down of the Indian Point nuclear plant, and replacing dangerous nuclear power with safe solutions like renewable energy and energy efficiency. The demo lasted just 45 seconds.
