How can carbon dioxide be considered a pollutant when it is a natural component of air?

High levels of acts as pollutant in the atmosphere.

Explanation:

Carbon dioxide is a natural component of air. It is produced by the human body metabolism and by other factors. However, concentrations reaching above normal levels is considered to be as a pollutant.

Carbon dioxide is produced as a byproduct of many industrial and commercial chemical synthesis. This emission directly reaches in the air and causes high levels of concentration in the atmosphere.

High levels of causes greenhouse effect, acid rain as well as global warming and thus, it is considered to be as a pollutant.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
