Microbial ecology is the study of the role of microbes which appear to be necessary for the functioning of life on Earth. Microbial ecologists seek to understand how microbes affect the environment on a global scale. Microbes probably contribute to global change, nutrient cycling, and ozone depletion.
Microbial ecology is the study of microbial interactions with plants and with animals and with other microbes.
Microbial ecology is an applied science. Knowledge of microbial ecology contributes to environmental protection, agriculture, mining, food production, and chemical and pharmaceuticals production.
Microbial ecology is a rapidly developing scientific discipline. The reasons for this include the realization that microbes are essential for a healthy environment; they are important in helping us understand the mechanics of evolution; and they are important in biotechnology.
