24 rocks = 105% of the carbon load How did you remove it?
At best your arguement is that you could have added 20 rocks but you only added 3. Matters not the road is still blocked with rocks.

"Black or white" is the rationalization for "do nothing". Which is the rationalization for the 150 gallons of gas I burned on the fishing trip is OK becasue still polluted less that company over there.

That company over there may be the plating company for Rvrfshr spoons, hard to find a ore toxic proces than metal palting. Even with the cradle to grave laws . I doubt anything you could do personally, would even come close to offsetting those pollutants. Well one could rationalize it away in their own mind.
