No doubt about drilling for oil being dangerous. That's one reason why u won't find any Sierra Club members or NY Times writers who have worked on a rig.
Although it's against my libertarian principals; there really should be a rule requiring basic mathematical competency for newspaper writers and environmental club types (I regard myself as an environmentalist but I don't need to be in a club of fools). I figure if they had that, then they could figure out the absurdity of their statements about the oil industry and 'clean energy'.
