Green plants release CO2 during the night as part of normal respiration/metabolism of internally stored carbohydrates.

In minimal amounts. You know as well as I do, the process of photo synthesis...nevermind, what is the point of your post?

The point is that nearly every living thing releases CO2 as part of normal respiration. It is NOT a pollutant. It is NOT appropriate for the thieving government to tax us for what is a completely normal process.

They take in much more CO2 than they respirate out as the CO2 is what plants use to make their mass; all the oxygen given off comes from the water taken up by the roots and the hydrogen separated to combine with the CO2 to form the celluose and the various forms of carbohydrate material.

Might as well say that, since fresh water is a limited resource and water vapor is the strongest GHG of all, that growing plants is a positive feedback fueling ever-accelerating AGW; ergo, we could cool the planet almost overnight by razing all plant growth and painting the bare surface white.
