Carbon dioxide IS a pollutant when it is out of proportion to plants and trees ability to utilize it.

If you know anything about plants and carbon it's that right now we aren't even half way to what is optimal for them, so yes it's out of proportion, the levels of carbon would need to triple for them to even come to optimal. They are literally built to suck carbon dioxide through the leafs, and they aren't stressed by "all this 450ppm carbon dioxide".

So why is there this scare about co2, among the Scientists? Why are they huffing and puffing this strawman?
