The atmosphere refers to the air envelop surrounding the earth. This parcel is involved in the care and sustenance of the earth’s massive activities. It sustains life because the envelop nurtures life by providing adequate air in which animals and humans alike breathe as well as provide adequate carbon dioxide needed for food to plants through the photosynthesis process. The atmosphere contributes in great measures to the water cycle, alternating massive water movements from the earth’s surface to the atmosphere through evaporation as well as aiding condensation of water vapour back to the earth. It acts as the balance of water circulation for basic life existence in the earth.
The atmosphere is a basic necessity for man as provisions of food,

It shields the earth thereby preventing massive temperature increase to the earth’s surface. The atmosphere is a part of man’s living that should be cared and given ultimate protection.
The atmosphere consists of about 78% of N2 as well as other substances. Figure 2.1 below shows the various composition of the atmosphere. Figure 2.1: Composition of atmospheric air
The atmosphere is stratified into different parts according to the distance from the sun and other parameters, Table 2.1 below shows the different parts of the atmosphere.
Table 2.1 Layers of the Atmosphere The atmosphere has experienced tremendous anthropogenic alteration of the composition of the atmosphere with the production and increase of certain substances that change the atmospheric profile. Man’s activities have increased substances in the atmosphere capable of trapping heat in a parcel-like system with debilitating effects. The demand and generation of clean and renewable energy resources have been on the increase the world over, this massive shift have given rise to significant gaseous emissions released into the atmosphere by the burning of fossil fuels (Wang et al.,
