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，似乎愈来愈壁垒分明，一边的人支持，另一边的人则是畏惧。支持者宣称，种植基因改造作物对环境伤害较小，而食用这种农作物制成的食品也完全无害。它们还说，基因工程让农作物在贫瘠的土地上也能生长，或可培育出更营养的食物。在不久的未来，全球人口快速膨胀，还得靠这方法解决粮食问题。持怀疑态度者则反驳，基因改造作物对生态环境或人体健康都有极大的风险，令人忧心，不该贸然接受。许多欧洲国家抱持这种态度，因而限制基因改造作物的种植与输入。主要的争议，集中在基因改造食物的安全性。然而，最近的科学研究又是如何看待基因改造食物的危险呢？答案，往往迷失在各种报导的争议中；但是在接下来的篇幅里，它们将呈现在你的眼前。

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

The world seems increasingly divided into those who favor genetically modified (GM) foods and those who fear them. Advocates assert that growing genetically altered crops can be kinder to the environment and that eating foods from those plants is perfectly safe. And, they say, genetic engineering－which can induce plants to grow in poor soils or to produce more nutritious foods－will soon become an essential tool for helping to feed the world's burgeoning population. Skeptics contend that GM crops could pose unique risks to the environment and to health－risks too troubling to accept placidly. Taking that view, many European countries are restricting the planting and importation of GM agricultural products. Much of the debate hinges on perceptions of safety. But what exactly does recent scientific research say about the hazards? The answers, too often lost in reports on the controversy, are served up in the pages that follow.
