CO2 Is Essential for Life On Earth

SEE HERE If you don't have plants you don't have animals and if you don't have plants and animals humans would have nothing to eat.  CO2 is essential for plant growth and the actual optimum level for plant growth is actually much much higher than the current level in the atmosphere.  You have to wonder what kind of scientists are so stupid as to consider CO2 a pollutant.  We should stop funding scientists that are that stupid.
