Answer:
BECAUSE IT IS NOT NECESSARY FOR ALL LIVING ORGANISMS.
Explanation:
TO be brief A pollutant is anything that causes harm to living organisms on earth, it could be dogs, cats or even humans. In as much as co2 is necessary for plants, its not so good for the species that are at the top of the food chain in the society.
to put this in comparison, lets say, something is important to 2% of the worlds population and harmful to 98% of the worlds population , it means that we all are going to conclude that that's not good for mankind because of the population ratio.
with that being said, carbon dioxide is important for plants and also important for making oxygen but we need to understand that if that gas is the only one exposed to humans, its going to be bad for our living, health and well being. more so, an abundance of carbon dioxide in the atmosphere would create a cover that traps heat and light energy from the sun, leading to a change in the climate and warming out the earth and oceans, thus, carbon dioxide is a pollutant.
