But even a meltdown or an explosion does nothing in regards to global warming...so a very little is different. It's part of the same socio-political dynamic by which certain segments of the population (in this case misguided environmentalists) try to get us scared of things which are incredibly small threats (in the case of nuclear power) to push forward a political agenda. If later technological or scientific advances disprove those fears, the science is labeled suspect (often using ad hominem or guilt by association in the reasoning), and the technology untested and unsafe. I mention this because the phenomenon permeates even the best popular culture (like Civ IV) and people should be aware of the cultural cues around them, and how inaccurate they often are. And it's not just nuclear...some other often overstated threats: Global Warming (overstated, not non-existant) Terrorism Nuclear proliferation Iran (in general) Communism/Socialism (somewhat less now than when I was a kid) Do some primary source research on any of these topics and you'll discover threats are less significant than the voices in the media would have you believe.
