One gallon of gas burned puts 18 pounds of co2 into the atmosphere... 18 pounds. we will all be crushed under the weight of it all.

I've never actually done the math on this, I've only seen this Stat on left wing sites like the EPA. Too much work to do it on my phone, so this'll be rough. A gallon of gas is about 6lbs. CO2's atomic mass is 44 (C is 12, O is 16), 3.7x the carbon input. So that gives us 22lbs,assuming gas is 100% carbon, and your engine is 100% efficient in turning your fuel into co2. And then add in the additives weight, you're probably looking at maybe 15lbs of co2/co per gallon of gas. Quick Google shows mature grassland will eat about 3000lbs of co2 / acre / year. So your gallon of gas will, roughly, feed an acre of grass for about 40 hours.

thank you for the calculations... i will give them the benefit of the doubt and say a full hour of nourishment...

insightful if they would ever take their arguments to a conclusion.
