As noted above, the premise is wrong. Using wood won’t control CO2. Mammals breath in oxygen, and exhale CO2. Trees breath in CO2 and exhale oxygen.
Easy. Break the cycle. Eliminate mammals. Population ZERO, accomplished. A Libs dream comes true, except that the Lib has been eliminated.
Uhhh. Wait a minute. Something is wrong with that premise, too.
[Imagine what a chart of a Liberal's mind would look like.]
