Microbesare described as single celled organisms. They are also known asmicro-organisms. They are everywhere. Microbes are in the air, on theground and on the food. Human beings need microbes to digest food,animals too need microbes to aid them in digestion, plants needmicrobes to grow, garbage also need microbes to decay (Fluit et al,2013).
Examplesof microbes include bacteria, fungi, archaea and protists. To be ableto see a microbe, one has to use a microscope. As much as somemicrobes are harmful to the health of a human being, most of them areactually harmless and humans cannot survive without them. It isimportant to note that microbes play a key role in the life of ahuman being. Microbes are widely used in food production to producedifferent varieties of food as well on preservation of food (Quinn etal, 2011).
Oneof the challenges facing farmers in the 21stcentury is the production of sufficient food. In most of developedcountries today, agriculture is facing the challenge of due to theuse of pesticides and herbicides, salinization as well as thedepletion of water resources. The effects of microbes in cropproduction in the world today is evident in that microbial diseasesare costly to the modern farmer. Other microbes such as nitrogen havepositive effects on crop production and growth. The provide diseaseresistance, aid nutrient intake as well as promote biodiversity(Quinn et al, 2011).
However,in a research done by U.S. researchers, bacteria including MRSA wasdetected on the nostrils of farm workers which then suggested thatthe use of antibiotics in farming posed a threat to their lives andcan is a deadly bacteria. The MRSA farms tend to focus on productionof cheap food and do not pay much attention to the health of theanimals, to clean meat production or general farming programs.Another research carried out by the U.S. Department of Agriculture in2010 spotted dangerous substances in the meat supply. Some of thesesubstances include pesticides, veterinary medicine and heavy metal(Fluit et al, 2013). .
Inconclusion, microbes have benefits. These include they aid in theproduction of medicine, they aid in food production, they aid inproduction of enzymes as we as aiding in the cleanup of sewerages. Itherefore suggest that human beings should use the microbes for theright purposes and they should avoid over-using or exploiting them asthese may endanger their lives. Therefore I conclude by stating thatmicrobes are both useful to the production of farm products and theyare also harmful as stated above.
