Greenhouse gases concentration is increased through time within different human and natural factors. Now a day¿s climate change and global warming is the major problem in the world. It is damage (destroy) a number of biotic components. It has also effect on microbial community structure, function and their metabolic activity. In order to fight (compromise) climate change using a number of methods are listed here. For example, microorganisms and other biological components have many potential roles for mitigation by contributing forward response. Microorganisms have a wide function especially used in greenhouse gas treatment and reduction through nutrient recycling processes. It acts as either generators or users of these gases in a good manner. Our planet is facing the problem of different environmental pollution. Microorganisms are essential for a key alternative solution to overcome challenges. Microorganisms are surviving in all place on the biosphere because of their metabolic activity is versatile; then come into existence in all over a range of environmental conditions. so microbes used as bioremediation of environmental pollutants.
