400 Potential Fukushimas?

'There are nearly 450 nuclear reactors in the world, with hundreds more either under construction or in the planning stages. There are 104 of these reactors in the USA 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 melt-downs 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.'
