This 'CO2 is plant food' talking point is dumb.
Do you think plants are made of only carbon and oxygen?
There's a cute little animated movie called "The Lorax" based on the Dr. Seuss children's book. During one scene there's a debate over whether to plant a tree in the middle of town. The bad guy, Mr. O'Hare, who sells bottled air, is complaining about how useless trees are and the pro-tree girl replies they make clean air for free.
O'Hare: They do not!
Girl: Yes they do. It's called photosynthesis.
O'Hare: Photo... she's making that up! That's not a real word!
For some reason that movie came to mind... anyway...
CO2 is not just 'plant food' but it is also 'plant air.' Photosynthesis uses the instability of chlorine (why plants are green) to convert CO2 into oxygen and simple sugars used for growth in the presence of certain wavelengths of sunlight. We, along with other animal life, use the oxygen to fuel our chemical processes and release the resultant CO2. It's called symbiosis; each depends on the other.
Plant growth rates are a function of 3 variables: amount of sunlight (in the proper radiation band), temperature (within a certain range), and availability of CO2. Decrease any of these and growth rates will decrease; increase them and growth rates will increase. Greenhouse operators have known and used this information for a very long time.
Plants do not have to be made solely of carbon and oxygen for this to be true. What you have done in this post is try to disprove a scientific theory which has existed for centuries on the basis of a completely unrelated scientific observation. That is in itself unscientific. It's like saying the speed of light is not constant because your house is painted blue.
Incidentally, I do not believe "dumb" is a scientific term either...

I will end it by saying: did it ever occur to you that you didnt need science to tell you the sun shines light and warmth upon Earth?

LOL... Obviously you have no idea that all lifeforms on Earth are carbon based...
Carbon forms the key component for all known life on Earth. Complex molecules are made up of carbon bonded with other elements, especially oxygen, hydrogen and nitrogen, and carbon is able to bond with all of these because of its four valence electrons. Carbon is abundant on earth. It is also lightweight and relatively small in size, making it easier for enzymes to manipulate carbon molecules.[citation needed] It is often[how often?] assumed in astrobiology that if life exists somewhere else in the universe, it will also be carbon based.[1][2] Critics refer to this assumption as carbon chauvinism.

Some people really need to brush up on their "science"...

You probably should have replied in that thread.

But tell me, what is the current field strength?

So if you're in a closed garage with your car running, you'll be just fine?
As long as it puts out carbon DIOXIDE instead of carbon MONOXIDE, yes, you'll be fine.
The eventual number of people who died in the Lake Nyos gas leak was put at more than 1,700.
Scientists debated the cause of the disaster for some time afterwards.
It was finally concluded that the lake's lower levels had become saturated by carbon dioxide gas (CO2) due to gaseous springs which bubbled up from the extinct volcano beneath.

Actually, no. You won't. CO2 kills.

A doctor there said they had been poisoned by a mixture of gases including hydrogen and sulphur.
He described the symptoms, including burning pains in the eyes and nose, coughing and signs of asphyxiation similar to strangulation, as like being gassed by a kitchen stove.
deeper breathing
twitching of muscles
increased blood pressure
headache
increased pulse rate
loss of judgement
labored breathing
unconsciousness (occurs in under a minute when CO2 concentration rises about 10%)
death
So. Preliminary guesses are preferable to further analysis? It's entirely likely that hydrogen sulfide was involved. But that's ok, go ahead and fill your garage with CO2, you'll be fine.
Please do a little research before challenging something this this.

You are the one who made the sweeping remark that CO2 kills... It doesn't, not at the levels they exist in Earth's atmosphere, and if you are going to say "CO2 kills" then you can also make another sweeping claim that "water kills"...
