The ghost town which once had a population of about 50,000 people, was given a few hours to evacuate in April 1986 as radiation streamed into populated areas after an explosion at the reactor.

There are 104 of these reactors in the United States and 195 in Europe. Imagine what havoc it would wreak on our civilization and the planet’s ecosystems if we were to suddenly witness not just one or two nuclear meltdowns, but 400 or more! How likely is it that our world might experience an event that could ultimately cause hundreds of reactors to fail and melt down at approximately the same time? I venture to say that, unless we take significant protective measures, this apocalyptic scenario is not only possible, but probable. Consider the ongoing problems caused by three reactor core meltdowns, explosions and breached containment vessels at Japan’s Fukushima Daiichi facility and the subsequent health and environmental issues.
