Even if 1% is man made we should take steps to fix it.
I have no sympathy for cooperate America belly aching because regulation would cause them to spend mega bucks to clean up their pollution.
I have no sympathy for the oil industry who pays our elected officials to speak on their behalf over this issue. The average American citizen does not have millions to pay these politicians to speak on their behalf.
When did we get to the point were are officials can be bought off by cooperate America?
You have no idea what 'cost effectiveness' is do you?
Let's answer this. Are you willing to lose your job, be forced into a smaller and less safe car, smaller colder in winter, warmer in summer home, and more expensive costs of living all for a dent in less than a 1% increase on a substance that has no hard evidence it does ANYTHING to the environment save making plants grow better?
Look at an 8th grade earth sciences book at atmospheric composition and see the percentage of atmosphere that is CO2. Then consider that mankind's contribution of that is even a minuscule fraction of a single percent of THAT. And you're trying to tell me that our contribution is the sole reason that the weather is going whacky???
Are you stoned, stupid or just ******* nuts?
