Grrrr, as someone who used to work on the design of nuclear power stations I kinda resent this thread.

Some questions you might answer to put things in perspective.

How many people die each year from bronchial troubles caused by pollution from conventional power stations? (It was 30,000 in England alone in the mid sixties)
How many trees are killed each year from pollution caused by acid rain from conventional power stations? Ask any Canadian.
Do we need trees to live?
What does happens to animals who live in the area inundated by a hydro lake? How many beetles, lizards turtles and so forth are left to drown? Of course that's NOT pollution, or is it?
Even with Chernobyl and Three Mile Island the scales are still heavily tipped against conventional power stations. (I didn't work on the design of either of those, in case you were wondering)
Nuclear power may not be the great thing that it was intended to be, but as an interim measure for ridding the earth of conventional power stations it may be the only thing that can save us.
