| In the last twenty years of the 20th century, the genetic engineering techniqueshave had a great advance in unmatched speed that there is no one can reach it. And ithas become the focus around all techniques in the world. This generation is not anaccident. According to the superiority of genetic engineering itself, this production isan inevitable result. There are many kinds of GMC in the world. The GMC like cotton, rice,soybean and corn which are insect,resistance and herbicide, has a much higher unit of output thenthe other varieties of crops. And it also has a great adaptabilityon the adverse in the environmental,made a great tremendous of economic and social benefits.With the continuous development of economic level, people pay a great attentionto the ecological environment nowadays. The safety of genetically modified products has alwaysbeen a controversial issue since it was appear. The development of transgenic technology is soshort, and when the GMC are growing in the nature, they have to make contacts with other species.But it is still uncertain about the result of such exposure. Being a part of the GMC, it has a greaterseverity of risk then other plants.In this development, this article will introduce the basis and purpose of the topics in the firstchapter, and then begin at the analysis of the characteristics of genetically modified crops in thesecond chapter. In the third chapter, I'll analyze and evaluate the current system of environmentalsafetyof genetically modified agricultural in China now. In the forth chapter, I'll analyze and learnfrom foreign experience, then put forward my own proposals on the construction of the transgenicbiosafetylegislation. |
