Farmers like to limit the use of more hazardous pesticides when they can but gm crops also hold appeal because they simplify operations reducing the frequency and complexity of pesticide applications and in some cases increase yields 农人总是希望尽量少用比较危险的农药，不过基改作物之所以吸引人，是因为劳作手续简化了降低施用农药的频率及复杂程度，甚至可使产量增加。
The question now is what will the consequences be so far no scientific studies have found evidence of gm crops causing superweeds and a 10 - year study reported in nature in february found no weedlike behavior by gm potatoes beets corn or canola planted in england 2001年2月自然杂志上有篇报告指出，在一个长达十年的研究里，英格兰栽种的基改马铃薯甜菜玉米或油菜，都没发现像野草那样能使近亲种受精的情形。
In calling for the return of terminator genes , supporters of gm crops note that genetically enhanced plants have as much or more potential as exotic species to invade surrounding ecosystems and drive wild populations into extinction . “ terminator technology is a near perfect way of controlling unwanted gm spread , ” insists geneticist william m 为了让终结者基因重见天日，支持基改作物人士提出的理由是，基因经过强化的作物要比外来种更有潜能侵犯周遭的生态系统，而造成野生族群的灭亡。
The innocent bugs birds worms and other creatures that happen to pass by the modified plants will gm crops pollinate nearby plants casting their genes into the wild to create superweeds that grow unchecked what are the odds that the genetically engineered traits will lose their ability to protect against insects and invasive weeds leaving gm plants suddenly vulnerable 他们想要知道的有： bt作物如何影响“非目标”生物，例如无害的甲虫鸟儿蠕虫以及其他恰巧路过的生物？基因改造作物是否会授粉给周遭的植物，使抗虫基因流入野地，创造出不受控制的超级野草？
