Solution(By Examveda Team)
Carbon-dioxide is not a pollutant normally.Carbon dioxide is not considered an air pollutant, as it occurs naturally in the air. However, the CO2 concentration in the atmosphere has significantly increased due to human activity. Carbon dioxide is a greenhouse gas; alongside nitrous oxide (N2O), and methane (CH4).
Carbon dioxide in the atmosphere warms the planet, causing climate change. Human activities have raised the atmosphere's carbon dioxide content by 50% in less than 200 years.
