[QUOTE="Eagle Eye, post: 2738672, member: 34489"] Im glad you brought this up. This happens to be my field. bear with me on this one Q1. where does the Carbon dioxide we breath out come from? A1: it came from the atmosphere, was fixed (taken up) by a plant and converted into a sugar using the energy of light and hydrogens found in water. So, that carbons cycles back and forth and there is no NET increase in C. Q2:Where does the carbon dioxide cars release come from? A2: Fossil fuels that have been locked away underground. So by releasing it, there is a NET increase in CO2. see? Yes, one would think that more co2 means more plant productivity (biomass), right? Not the case. Plants are most often not limited by Co2, instead they are limited by Nitrogen or Phosphorous or some other nutrient. So, more co2 in the air will only increase plant productivity to a degree, until plants are limited by another nutrient. Either way. we are increasing the NET Co2 concentration by taking the C that was locked away ouderground and burning it, thereby releasing it into the atmosphere. I hope i was clear enough [/QUOTE]
