A classic from last year on the HotCopper S&M forum.A contribution to the S&M forum from Moondoong, the self-described 'busted-ass mining engineer'. He thinks everything on this list is equally unlikely and not at all 'alarming'.
He equates AIDS (one of the world's biggest killers) and the hole in the ozone layer (a disaster in the making but thankfully being addressed) with an alien invasion and an asteroid striking earth. Alar did pose a risk, albeit nothing like smoking tobacco. Y2K was a real problem but not one that mining engineers would necessarily understand. I don't know what was in his mind when he added magnetic pole shift or solar flares. They happen all the time. (Does anyone know what Planet X refers to?)

About twice as many science and medicine visitors agreed with moondoong (going by the "thumbs up" he was awarded) as thought he was talking through his 'busted ass'.
Yep, that's HotCopper :(
