 Microorganisms are tiny, small living things which can not be seen with eyes. They spread everywhere around the world. Most people think that microorganisms are harmful to the environment. Humans exploit these small living things hundreds of years ago. Science has developed and scientists have established new science related to microorganisms, it is called microbiology. In this essay, I will talk about one of the oldest and most widespread microorganisms in our planet, bacteria. Bacteria lives everywhere, in air, hot springs, and in our bodies. Some bacteria are harmful and some of them are helpful. Biologists use helpful bacteria in several ways. In my essay, I will focus on some uses of bacteria in medicine, environment, and industrial. Bacteria contains many distinctive characteristics that makes it very important for the environment. It is considered one of the basic decomposers in the environment because bacteria analyzes dead organisms and converted to simple organic compounds which is essential for plants to manufacturing new foodstuffs. In addition, to rid the environment from the accumulated corpses. Furthermore, bacteria used to get rid of waste from factories and homes that includes heavy toxic elements such as lead and mercury, which cause great risks to the environment and living organisms. But the existence of bacteria helps to convert these heavy elements to an organic compound which called methane. Methane is safe for the environment, and it uses as an energy source in wide range. Additionally, Scientists were able to combat marine pollution by a biological solution, using some types of bacteria that have the ability to absorb oil spills. Also, they found that some types of bacteria for example, Pseudomona, Arthrobacteria and Cornybacteria can transfer oil slicks to droplets of water. As well, bacteria plays a significant role in the process of atmospheric nitrogen fixation, and that leads to increased soil fertility and production....
