Biotechnology....什么来的
Biotechnology is most briefly defined as the art of utilizing living organisms and their products for the production of food, drink, medicine or for other benefits to the human race, or other animal species. Technically speaking, humans have been making use of biotechnology since they discovered farming, with the planting of seeds to control plant growth and crop production. Animal breeding is also a form of biotechnology. More recently, cross-pollination of plants and cross-breeding of animals were macro-biological techniques in biotechnology, used to enhance product quality and/or meet specific requirements or standards. The discovery of microorganisms and the subsequent burst of knowledge related to the causes of infectious diseases, antibiotics and immunizations could probably be counted among man’s most significant, life-altering discoveries.
However, the most modern techniques in biotechnology owe their existence to the discovery of DNA and several
techniques essential for gene cloning. Current scientific methods are more specific than historical techniques, as scientists now directly alter genetic material with atomic precision, using techniques otherwise known as recombinant DNA technology.?

Biotechnology in IndustryDifferent biotechnological advances can be found in nearly all sectors of industry today. There are, of course, the obvious medical, pharmaceutical and food industries. Advances in biotech are being used to determine cause and effect of various diseases and are used in the production of drugs. The production of foods is enhanced by biotechnological advances that improve crop yields, introduce in-situ insect resistance and provide new ways of food preservation. Technological advances also include biodegradable packaging and built-in bio-indicators of food contamination. In the environmental sector, biotech has played a role in remediation of contaminated land, water and air, pest control, treatment of industrial effluents and emissions, and acid mine drainage.
Biotechnological Advances and the Human RaceMoral debates in
bioethics continue to surround the field of biotechnology. The public response to issues such as the value of genetically-modified organisms (GMOs), versus the risks involved in their release into the environment, more-or-less quenched the enthusiasm of the bioremediation industry for GMO research, in the early 1980’s. Genetically modified foods (GMFs) continue to be produced, but with more and more governments clamping down on production and distribution and answering calls by the public demanding strict testing and labeling procedures.
Exciting new developments are being made in bio-fuel research, at a time when fossil fuel prices as going through the roof. However, the question of whether a diminishing supply can meet the ever-increasing demand is under debate by those who don’t believe the fossil fuel crisis is imminent. If they are correct, there is still some question of whether the cost of biofuel research and development is worth the effort.
Finally, there are the highly publicized and emotional debates surrounding the use of human embryos and
stem cells for genetic research. Although the benefits of such research are obvious to most, the cost to human rights, morality and religious integrity are too high for some.
The Current State of AffairsDespite on-going debates and occasional road-blocks, the biotech industry continues to persevere. Anyone looking for a
career in biotechnology can choose from a wide variety of scientific and non-scientific disciplines, ranging from molecular genetics to chemistry, to business management and law. Almost every aspect of human life is touched by biotechnology. We continue to look for ways to improve our health, increase food production with an eye to feeding the poor in less industrialized countries, and clean up our environment. Biotechnology offers more environmentally sound solutions to the onslaughts of the industrial revolution, and a wealth of hidden answers to our most intriguing medical questions. For those reasons, biotech research will carry on and the industry is here to stay.
