Biotechnology Definition of biotechnology: "...any

technique that uses living organisms (or parts of organisms) to make or modify products, to improve plants or animals, or to develop microorganisms for specific use" (Wells, Poszywak, & Dunham, 2000, p. 63).

Biotechnology

However, biotechnology has also caused society to examine its values by expanding toward the implementation of technologies like "designer babies," replacement limbs and organs grown from stem cells, biological warfare agents, and the artificial extension of life by slowing the aging process.

Environmental ApplicationsBioremediation is using organisms in

processes that help to clean polluted environments. Biological controls, biosensors, biotreatment, biorestoration, and phytoremediation are all means of using biotechnology to clean or protect the environment.

Environmental Applications

Agriculture and Biotechnology

Genetically altered crops and animals are among the most significant applications of biotechnology. Genetic engineering has enabled both crop and livestock producers to create improvements to stocks and implement them in one or two generations.

Agriculture and Biotechnology

Hairless Chicken will save money by decreasing the time and tools used to pluck the hairs off chickens

We already eat genetically altered vegetables such as tomatoes

Biotechnology Areas Bioprocessing Biological organisms are also

important in the production of products in industry. Bacteria are especially useful in purification and separation processes. For example, one particular type of bacteria is being used in the mining and refining of gold.

Genetic Engineering

Genetic engineering is based on the manipulation of genes (Grace, 1997). Genes hold the blueprint for how every living thing grows, looks, and behaves. If there were two organisms, say bacteria, and each had different but desirable characteristics, then the genes responsible for each characteristic could be combined in one of the organisms.
