Environmental Microbiology is the study of microorganisms and their roles in the environment. This field explores how bacteria, fungi, and viruses interact with soil, water, and air, influencing ecosystems and nutrient cycles. These tiny organisms are essential for processes like decomposition, which helps recycle nutrients, and bioremediation, where microbes break down pollutants. Researchers in Environmental Microbiology also examine how human activities impact microbial communities. For instance, pollution can alter the balance of these microorganisms, affecting their ability to support plant growth or clean up contaminated sites. Understanding these interactions helps us protect our environment and promote sustainability.
