Genetically modified food safety
Abstract:In the 20th century is called the age of life science and biotechnology ,People have to share to the biological high-tech brings a lot of convenience ,And look forward to them to prevent the disease, improve the nutrition level, improve the quality of life, meet the needs of the family, bring more benefits to extend the healthy life, etc. In the meantime, however, It has been strongly felt Biological high-tech challenge to traditional moral and ethical system, Seeing or feeling to the resultant of the society and legal .
As we all know , modern biotechnology has brought human numerous benefits ：through the application of biotechnology , a broad and significant increase of food production can be happily seen at global agricultural production . But when we enjoy the enormous benefits of the GM food , a new but a alarming problem also came that if these food is safe enough for people? If something seriously happened , what can we do? Maybe you can find some answer in these thesis.
Key Word :modern biotechnology GM food safety
One: introduction
What is biotechnology ? maybe not too mang people know is definition accurately . biotechnology is a technology which can reform and make the use of natural lives on the ingredient of them by taking advantage of the research finds in life sciences which can greatly follow the will of people . in its purest form, the term “biotechnology” refers to the use of living organisms or their products to modify human health and the human environment .
Biotechnology in one form or another has flourished since prehistoric times . When the first human being realized that they chould plant their own crops and breed their own animals , they learned to use biotechnology . the discovery that fruit juices fermented into wine , or that milk could be converted into cheese or yogurt ,or that beer could be made by fermenting solutions of malt and hops began the study of biotechnology . when the first bakers found that could make a soft , spongy bread rather than a firm , thin cracker , they were acting as fledgling biotechnologists . the first animal breeders , realizing that different physical traits could be either magnified or lost by mating appropriate pairs of animals , engaged in the manipulations of biotechnology .
Two: Status of genetically modified foods :
As we know，modern biotechnology has brought human numerous benefits ：through the application of biotechnology a broad and significant increase of food production can be happily seen at global agricultural production . Since 1983 when the time human got transgenic tobacco , potato by using recombinant DNA technology ，the plant genetic engineering technology in the world has achieved rapid development of transgenic plants for research and development , which has
