Ozone depletion and its ultimate effect, global warming are main concerns in climate change in the world today. The phrase ‘climate change’ is growing in preferred use to ‘global warming’ because it helps convey that there are changes in addition to rising temperatures. Accumulation of greenhouse gases in the atmosphere depleted the ozone layer and consequently causes global warming. Gases that trap heat in the atmosphere are often called greenhouse gases. That the Earth has warmed by 0.74oC over the last hundred years and that around 0.4oC of this warming has occurred since the 1970s is unequivocal fact that leaves little room for doubt that human activity is the primary driver of these changes (May, 2006). Among factors that emit the greenhouse gases into the atmosphere are burning of woods (fuel woods) and deforestation. Removal of plants on the surface of planet Earth is no doubt contributing greatly to the accumulation of greenhouse gases and thus the global warming.

World leaders, public health specialists, engineers, atmospheric chemists, hydrologists, quantum physicists, mathematicians, botanists, zoologists, have all being striving to stop further release of more greenhouse gases into the atmosphere, and in the occurrence of these gases, they are trying to purifying or cleansing them.

One of the cleaners or purifiers that can be employed is stomata. Stomata are microscopic openings or pores located majorly on the abaxial or lower, and adaxial or upper surfaces of leaves of plants. Though sometimes, stomata are present on the stems, petioles and sepals but in very small number.
