I just heard President Obama say in simple terms that carbon emissions "pollute our water and air". He said exactly that. Lord knows what he actually meant. It should be stated that at this moment, I am drinking a carbon-polluted can of Diet Code Red.
In an age where it is becoming apparent that atmospheric carbon does not increase terrestrial, ground-level temperatures (there is laboratory evidence that CO2 may in fact be a solar energy deflector akin to O3) we do not need to confuse CO2 with actual pollutants. Whatever your political (as opposed to scientific) position on CO2, it must be conceded that actual toxins such as PCBs need to be handled and regulated in very different ways.
How long before we simply referr to anything we do not like as an addiction?
