转基因作物的生态环境安全性

转基因作物是一把“双刃剑”,既带来了巨大的经济效益,也给自然生态环境带来了一些不利影响。一是对非靶标生物的影响;二是基因逃逸问题;三是转基因作物生存优势的影响。但是,种植转基因作物可以减少农药对人畜的伤害,可以进行保护地耕作,可以利用转基因作物消除环境中的重金属等污染物。为此,必须对转基因作物的研究和利用采取一种系统的思维方式,对其过程要进行严格管理和监控。

Ecological Environment Safety of Genetically Modified Crops

Genetically modified crops can bring huge economic benefit, but they also cause harmful effect on natural ecological environment. First, it may affect non-target organism. Second, problem caused by gene flee. Third, superior living ability affected by genetically modifying. Though they may cause such problems, they may reduce the harm of pesticide to human and animals and avoid metal pollutions. They can be planted under protection. So the studies and utilization of genetically modified crops must be seriously administrated and monitored adopting a systematic concept.
