Early in 1999, the United Kingdom Government announced since 2000 for a project entitled "farm assessment" series, by the fact that scientific findings of scientific research, to quell public concerns about genetically modified crops and reduce contention, the rapid promotion of GM crop cultivation area. 4 years after its findings seemed more genetically modified crops. However, in this series of studies that only genetically modified corn is believed to be safe, conducive to biological diversity. This is the latest subject of scientists.
Recently published by the United Kingdom the Royal Academy of Sciences of Biology Newsletter reported that the United Kingdom of a four-year assessment of the "farming" series of research findings, genetically modified crops on the environment and wildlife. A study on the evaluation of "farming" was regarded as the world's most extensive safety testing genetically modified crops, the $ 550 m (950 million). The series of a transferred to intensive herbicide resistance gene of winter rape trials show that its natural hazards than traditional rapeseed, unsafe and not conducive to biological diversity. Researchers in the United Kingdom 65 areas planted winter transgenic rapeseed and traditional rapeseed (normal rape), and wild flowers, weeds and seeds, bees, butterflies and other insects and animals. In the past few years, researchers observed 100 million species of weeds, 200 million species of insects, conducted a total of 7000 visit. The fact that traditional land and genetically modified oilseed rape rape of weeds, the overall number of counterparts, but the transgenic rapeseed field of broad-leaved grass quantity significantly less than traditional rape; this result accordingly attracted another result that transgenic rapeseed field of bees, butterflies, songbirds (e.g., Sparrow) and other biological less than traditional rape. Where transgenic rapeseed in Butterfly over conventional rapeseed minimizes 2/3, the bee has been halved.
For the quantitative results of the experiment, the researchers give the explanation is that transgenic rapeseed containing powerful herbicides, farmers will have to let go of gene in transgenic rapeseed and use more extensive herbicide, which killed many broad-leaved grass plants and flowers; also because of the food chain and the dependence of the chain of survival, broad-leaved grass of bees, butterflies, songbirds and other organisms naturally decrease. Of course, the United Kingdom has not yet been reached on a large scale study of "one-sided" entirely, but at a period of 4 years of study, the researchers were on transgenic winter, and spring oilseed rape and beet, maize was studied, in which 4 types of genetically modified crops in the only transgenic maize is believed to be safe, conducive to biological diversity. However, even this study concluded that the genetically modified crops to the conclusions of the biological diversity, also considered not very optimistic, because in comparison to traditional crops use of herbicides, the EU banned the harm to wildlife, especially large.
Faced with such a large-scale experiment results, that is, genetically modified crops is detrimental to the environment and biodiversity, genetically modified crops in the United Kingdom and the EU do? the opinion that the test results for United Kingdom transgenic crops (product) to create "coffins" knocked into a nail, genetically modified crops and products in the United Kingdom and the EU to promote at least slow down or even tho eventually being 寢.
However, on the other hand, is keen on promoting transgenic crop of researchers in the United Kingdom questioned the large-scale study of accuracy, objectivity. Perhaps some researchers will carry out a study on proof to the contrary conclusion of transgenic crops are safe. However, genetically modified crops and products must be in resolving security issues and can guarantee the quality before you can promote and consumption.
At present, China has allowed first planting transgenic rice, of which priority is with wild rice gene Xa21 of blight resistance in transgenic rice. Xa21 comes from the same kinds of rice, that is, from the African wild rice; it is through international tropical agricultural biotechnology laboratory (ILTAB) and the United States to the joint efforts of the Rockefeller Foundation, in 1995 in Africa Mali's wild rice in the identification and cloning of the normal gene Xa21 of rice in the environmental and ecological security. However there is also a public opinion at home and abroad, in the face of the United Kingdom study on "genetically modified crops on a large scale is detrimental to the environment and wildlife," concluded that China's transgenic rice will be security tests.
The pros and cons of genetically modified crops will undoubtedly continue to debate the issue, however, only the safety of genetically modified crops demonstrated, low cost and high profit, to most countries in the world. This is the future of genetically modified crops.
