Can Bioenergy from Forest Products Significantly and Sustainably Reduce Fossil Fuel Use?: A thoughtful review of the subject suggests not.

Subject Index Summary
Fluctuating Asymmetry: Higher concentrations of atmospheric CO2 tend to reduce fluctuating asymmetry in plant leaves, leading to more symmetrical leaves that appear to be less susceptible to attacks by herbivores.
