转基因作物对环境影响的讨论

The Risk Assessment of Transgenic Crops to the Environment

随着转基因作物的不断推广 ,转基因作物对环境的影响受到越来越多的关注 ,其中包括转基因作物潜在的侵袭力 ,基因漂移 ,对生物多样性的冲击 ,对农业生产的影响等等。这些议题具有跨学科性和高度的复杂性 ,要正确评价它们 ,就必须设定一个合适的标准作为参照。通过传统育种方法培育的新品种对环境的影响成为最合适的参照 ,这些新品种被广为认可 ,是现代农业重要的组成部分。在许多实例当中 ,转基因作物对环境的影响与通过传统育种方式所得到的新品种对环境的影响非常相似。通过比较对转基因作物进行恰当评价 。

With the release of GM crops, there is a multitude of concerns about the impact of GM crops on the environment including potential invasiveness, vertical or horizontal gene flow, effects on biodiversity and the agricultural production A crucial component for a proper assessment is defining the appropriate baseline for comparison and decision for GM crops The best and most appropriately defined reference point is the impact of plants developed by traditional breeding The latter is an integal and accepted part of agriculture. In many instances, the putative impacts identified for GM crops are very similar to the impacts of new cultivars derived from traditional breeding. With the appropriate assessments and comparison,the GM crops will be recognized thoroughly.
