Abstract: Air pollution has wide-ranging and deleterious effects on human health. The Global Burden of Disease study has described the worldwide impact of air pollution with as many as 5.5 million deaths [1] in the year 2016. The main air pollutants are in gases forms, particles in suspension, different ionizing radiation forms. The gases forms are oxidized and reduced forms of carbon (CO2, CO, CH4), of nitrogen (NO2, NO, N2O4, NH3, NH4+), SO2, O3, C6H 6 vapors, Hg, volatile phenols, Cl2, etc. The particulate forms are PM10 and PM2.5 particulate matter, heavy metals with toxic effect (Pb, Ni, Cd, As), polycyclic aromatic hydrocarbons PAHs, etc. A study across the Chicago region determined that trees and plants removed approximately 17 tons of carbon monoxide (CO), 93 tons of sulfur dioxide (SO2), 98 tons of nitrogen dioxide (NO2), and 210 tons of ozone layer[2]. With more than 12 thousand people residing per square kilometer indicates the limited availability of usable land area and forest cover being less than 23.68% [3] forced us to think on the principle of maximum vegetation in minimum land area. Based on this principle Botanical Tower is the solution which is expected to increase the Green cover up to 11 times of the original area.
