If CO2 is a pollutant, then elimination of exhaling humans is a logical focus for Sierra Club.

  Except that these CO2 emissions are exactly balanced by CO2 absorption by the plants that produced our food. If you are objecting to food produced directly from fossil fuels, or methane emissions in agriculture, then yes those are valid targets to be addressed.

    CO2 is 0.04% of atmosphere. More atmospheric CO2 is followed by more plant growth, so you are right that it does balance.

      If more CO2 were balanced by more plant growth, CO2 concentration would not be shooting up, decade after decade. But it is.
