GENETICALLY MODIFIED FOODS: Are They Safe?

- Are genetically modified crops an environmental dream come true or a disaster in the making? Scientists are looking for answers

基因改造食物安全吗？

- 鼓吹基因改造作物的人说，这类作物不像传统作物，需要的有毒农药较少，对环境有利。但令批评者担忧的是潜在的风险，他们想知道所谓的利益究竟有多少。到底基因改造作物是环保美梦的实现，还是一场正在形成中的灾难？科学家正积极寻找答案。

人们对基因改造食物的态度，似乎愈 The world seems increasingly 来愈壁垒分明，一边的人支持，另一divided into those who favor 边的人则是畏惧。支持者宣称，种植genetically modified (GM) foods and 基因改造作物对环境伤害较小，而食those who fear them. Advocates 用这种农作物制成的食品也完全无
