“But Life”



If you think carbon is a poison to be eradicated, when every human is 18% carbon, all your policy options are scary.


Of 118 known elements, carbon: bonds with the most other elements; is the 2nd most abundant in the human body; is the 4th most abundant in the universe.


Objections and Replies

Decarbonisation. —

Fertilization. More carbon dioxide means more fertilization—
☞ You can have positive and negative things going at once, and it’s the net balance that matters.

Greening. The world is greening nowadays, and that’s good—
☞ It’s indeed good that you accept that it is warming. It’s also important to realize that CO2 benefits plants only up to a point, and it’s just one factor.

Grow. Plants don’t grow without CO2. They don’t grow MORE without MORE—
I doubt that photosynthesis proceeds by modus tollens. From the absence of CO2 you can’t infer anything regarding the presence of CO2.

Life goes on. —

Plant Food. CO2 is plant food—
The Calvin Cycle is more complex than that.

Pollution. CO2 cannot be pollution, as it’s what you exhale—
Pollution is best considered an activity of man, which directly or indirectly results in the addition to water, air or soil, of matter or energy which has a deleterious effect on living organisms or structures it is desirable to preserve, or which reduces the quality of water, air or soil for any subsequent use [V.S. Russell, 1974-07].


{} Incompatibility. It would be hard to appeal both to the fact that CO2 is life and that it’s a trace gas. Yet they are often seen hand in hand, or one after the other. Pointing out the contradiction helps.

{} Life goes on. See #ButAccelerate.
