Yes, and like I said, it can also be a pollutant to all forms of life at levels above physiologic, which I have already given, for humans. I have also shown that CO2 can kill, when levels are above physiologic. I have also stated that water is necessary to life, but can also be a pollutant.
CO2 is a pollutant in excess, do you deny? Do you deny that CO2 can kill you? I will ask you a direct question, gs, can CO2 kill you? Too much water can kill you, too much of anything can kill you, which is why we set physiologic levels, or levels that can be maintained.
The problem is that we don't know physiologic levels for every friggen biological entity on this planet. We also don't know how increased CO2 will affect biological competition. We don't know how increased CO2 will alter the landscape of crops and green life.
Once upon a time, nitrogen was the best thing ever for plants... until we realized that weeds are able to better utilize nitrogen than the crops we were trying to increase in size.
There is a lot we don't know, and until we have some better understanding, it isn't wise to just go half cocked out into the world and increase CO2 concentration. The last time had super high CO2 concentration, we had quite a different landscape of green life... in fact, I think we only have about 7% of the plant population.
But, one thing we do know, though, is that CO2 above a physiologic amount will end you. Do you disagree?
Your post is so full of wrong or misleading items
that it's dificult to tell where to start.
Nevertheless I'll cover some of the more egregious
errors;
CO2 is such a tiny concentration of the atmosphere
that its overall impact is neglible. 380ppm sounds real
scary, until you realize it is .00038 concentration.
That is .038 of 1%.
Not only that but man made CO2 is only a small fraction
to the total CO2 in the atmosphere rendering the whole
political discourse almost unworthy of attention.
Considering that man made atmospheric CO2 recycles
back into the oceans or is utilized by plants within five
years, there is no realistic equation where CO2 would
ever become harmful in our planet's atmosphere to any
plant or animal specie.
I still didn't see where you named a particular level
where CO2 would become physiological (who made up
that word anyway?) nor have I seen you list any plants
and animals that have been killed by CO2 as you have
claimed.
Being killed by CO2 in some sort of closed environment
would be feasable but not realistic in real life situations.
Nitrogen depleted soils will not produce corn crops,
that's why corn farmers rotate with legumes such
as soy beans to replentish nitrogen in the soil and
use weed killers such as 'roundup.' Again, fertilizers
are used to increase crops of all sorts. You wouldn't last one year as a farmer with your idiotic doctrine.
I disagree that CO2 should be called a pollutant for
political purposes.
If you consider it all in REALISTIC terms, CO2 comes
nowhere close to being a pollutant.
