Hi
I'm e new member and hope my firs post isn't to foolishness. I have a
question regarding CO2 emission from cars or other carbon combustions.
I realize the problem with co2 emission in large cities and in cold
winters but what about areas where there is vegetations, would the
vegetations grow better with more co2 emission or not? The specific
gravity of co2 is 1.5 therefore it should flow down to the ground not
up in the atmosphere and for plants to grow they need co2 as one
element of the photosynthesis.
Have I missed something or is my assertion correct.
