Probably right about the lunch, but I don't think it is right about the
plants. They are not "faster growing" in the sense of being engineered.
They use the CO2 for fuel. Has the benefit (as noted finally by our
esteemed gummint) of sucking out CO2, puttin in Oxygen. In other words,
there is no free lunch involved.

But maybe somebody with biology background can enlighten us.
