Dan,
How many damn smokestacks do you see scattered throughout the countries of the earht? How many industrialized countries can you count? How much deforestation takes place? How many places have been burned, cleared, paved? What is the threshold, and how close are we to it, that endangers us? At what point to you drop your asinine claims that nothing is wrong, there is no danger, change is not happening and no response is needed for this changing atmosphere?
A child could put two and two together but you guys... no it's gotta be refuted and argued no matter what common sense screams out. If Bush has a special interest group tell you that second hand cigarette smoke is not dangerous I suppose you would then condone teachers and students smoking in school? Classrooms full of exhaled smoke, no problem, tell your kids to just grin and bear it? Try to picture the earth as a smoky room, who needs it? Who wants it? You sound like the fools who said the Levees are fine in New Orleans, c'mon man give it up, grow up!
