It is investigative journalism and as everyone knows you don't need to be a scientist to do that.
Well then don't call yourselves the "Union of Concerned Scientists" when
most of you are not. Make it the "Union of Concerned Analysts" which
most of you are, or the Union of Concerned Investigative Journalists" which
all of you are not. But of course those names don't add that veneer of respectability.
I'm not disputing the figures, but you are hardly likely to get an unbiased view from that "union". They aren't going to tell you, for example, that coal mining (0.15 deaths per million production hours) is only marginally more dangerous in the US than other forms of mining (0.1 deaths per million production hours) and that the industry that kills most workers is fishing. They aren't trying to shut iron or copper mining down. Or get us to stop eating tuna.
