GW happens naturally, and there is nothing we can do to either cause nor prevent it. AGW is a big lie.
The CO2 emitted helps plants to grow better with less water, a great help to agriculture.
There is virtually no CO2 in the atmosphere.
78% = Nitrogen
21% = Oxygen
.04% = CO2
.96% = All other trace gases
Sorry, but unless it's plutonium....4/100ths of a percent is essentially nothing.
In low concentrations, CO2 is neither a toxin nor a pollutant.
