This is an old furphey.

The real problem is not the production of CO2 since most living things
produce it constantly.

The problem is the production of CO2 where the carbon atoms have been
sourced from fossil fuels (coal, shale, oils, natural gas) or from calcium
carbonate (acid-rain on limestone), which increases the number of carbon
molecules in the biosphere.

Cows and sheep don't do this, and nor do humans, or other living things.

This comes from industrial production of energy, using non-biomass fuels
(those with carbon atoms in the hundred-year carbon cycle) as a source.
