Explanation:
The three major air pollutants are Carbon monoxide(CO), Particulate Matter(PM10, and PM2.5) and Ozone(O3).
1.Carbon monoxide is colorless, odourless gas, mainly produced due to incomplete combustion of fossil fuels. CO has a great affinity for blood oxygen carrier, haemoglobin, forming carboxyhemoglobin. This substance is very harmful for humans. It can cause headache, dizziness, weakness, neusea, vomiting, and finally loss of consciousness.
2. Particulate matter(PM) are particles of certain size which when enter our body can cause a lot of damage. PMs are linked with pulmonary and cardiac disease. It initiates a lot of lungs and heart diseases. Depending upon the level of exposure PMs can also cause premature deaths.
3.Ozone is an allotrope of oxygen generally found in upper atmosphere in the stratosphere, protects us from harmful ultra violet rays of the sun. The ground level ozone (GLO) are harmful to human health. Ozone can cause risk of respiratory disease like Asthma.
The correct answer is - ozone.
The ozone is essentially three molecules of oxygen, or O³. This gas is crucial for the life on the Earth because it is the one that manages to filter out big portion of the UV radiation from the Sun which is extremely harmful if its too strong, as it will contribute to the dying out of pretty much every living organism.
While the ozone layer in the stratosphere is very useful, the ozone in the lower parts of the troposphere is actually considered as pollutant. The reason why it is considered as pollutant is because it is very harmful if inhaled, and it also heavily damages the plants.
Drought and desertification are closely related phenomena. Persisting over months or years, drought can affect large areas and may have serious environmental, social and economic impacts. While drought is a natural phenomenon, whose impacts can be exacerbated by human activities that are not adapted to the local climate, land degradation is the process of turning fertile land into less or non-productive land. In extreme cases in drylands this is called desertification. Land degradation and desertification are complex phenomena driven by un-adapted human activity in combination with land and climatic constraints. Inappropriate land use, such as monocultures, and unsustainable land management practices, such as deforestation, unsuitable agricultural practices and overexploitation of water resources), can cause land degradation that can be further aggravated by drought.
