You are rigth regarding CO2 to certain extent but burning fossil fuel more so coal for energy generation generates much more pollutants than CO2 - will not go into it as it is a very wide spectrum with SO2 the more common.

Hi amounts of CO2 made our water reservoirs, lake and oceans more acidic which destroys life form in those water bodies including plants

On top of that farm animals emit substantial amount of CH4 and decomposing waste from human activity do the same those gases are the more potent than CO2 which is mere a byproduct of producing energy

one average power plant produces;

10,200 tons of nitrogen oxide (NOx), as much as would be emitted by half a million late-model cars. NOx leads to formation of ozone (smog) which inflames the lungs, burning through lung tissue making people more susceptible to respiratory illness.

720 tons of carbon monoxide (CO), which causes headaches and place additional stress on people with heart disease.

220 tons of hydrocarbons, volatile organic compounds (VOC), which form ozone.

170 pounds of mercury, where just 1/70th of a teaspoon deposited on a 25-acre lake can make the fish unsafe to eat.

225 pounds of arsenic, which will cause cancer in one out of 100 people who drink water containing 50 parts per billion.

114 pounds of lead, 4 pounds of cadmium, other toxic heavy metals, and trace amounts of uranium.

>>CO2 is not a pollutant at all. CO2 is not just natural, it's an essential ingredient for life<<

Lots of things natural, essential things can be pollutants, depending on the context or quantity. The oceans are naturally full of salt, but fresh water has much lower concentrations. Thus winter road salt runoff becomes a pollutant in fresh water.
