ABSTRACT
There exists an enormous pressure on the earth to protect its natural environment. Human activities, increase in human needs, and sophistication lead to deterioration of the natural environmental system. Consumption of electricity, food, clothing, etc., is steadily raising, leading to a continuous growth of related industries. So the amount of greenhouse gas (GHG) emission is also continuously increasing. Excessive emission of GHG elicits pollution and worsens the condition of nature.1
