    That's probably true.

    That's not true. Burning coal pollutes air horribly, and not just
    a few greenhouse gases, but really toxic stuff including Uranium
    and Thorium.

    Also false. Uranium is a byproduct of coal mining, and becomes
    concentrated when removed. Putting it back that way is unsafe.

    Mostly true, though coal tar is rather nasty stuff.

    That's mostly true. Coal burning kills millions of people slowly,
    not all at once.

    That's fair.

    That's a fair assessment too, but I think the relative costs are
    often exaggerated by ignoring the substantial costs of burning
    fossil fuels. Overall, taking all risks into account, nuclear
    power still comes out a winner by a /large/ margin.
