Why don't people care about coal? Because they're ignorant and scientifically illiterate, that's why. Peak oil is not an energy crisis. It is a liquid fuel crisis.
I don't think ignorance can explain the people's disregard for the deaths caused by coal. I rather think, these 75 people per GWa are a price most would be willing to pay. The problem is the wrong perception that a few grams of plutonium would kill millions if they came in contact with water, so people think a radwaste repository much more dangerous than it really is. Three decades of propaganda by liars like John Gofman have pretty much ensured that.
