转基因食品的优点和缺点
转基因食品有较多的优点:可增加作物单位面积产量;可以降低生产成本;通过转基因技术可增强作物抗虫害、抗病毒等的能力;提高农产品的耐贮性,延长保鲜期,满足人民生
活水平日益提高的需求;可使农作物开发的时间大为缩短;可以摆脱季节、气候的影响,四季低成本供应;打破物种界限,不断培植新物种,生产出有利于人类健康的食品。
转基因食品也有缺点:所谓的增产是不受环境影响的情况下得出的,如果遇到雨雪的自然灾害,也有可能减产更厉害
英文
The advantages and disadvantages of genetically modified food
Genetically modified food has more advantages: they can increase crop yield per unit area, Reduces the production cost, Through the transgenic technology can increase crop pest-resistant, antiviral ability; Improve agricultural resistance, prolong storage sex minimal, and meet the people's life
Living level rising demand; Can make the crop development time is much shorter, Can cast off season, the influence of climate, the four seasons low-cost supply; Breaking boundaries, and constantly grow new species species, produce beneficial to human health food.
Genetically modified food and disadvantages: the so-called yield is not subject to the environmental impact of the circumstances that, if encounter sleeting of natural disasters, likely also cut worse

优点:可增加作物单位面积产量,降低;打破物种界限,培植新物种,生产有利于人类健康的食品.缺点:有研究表明,转基因食品对的免疫功能有损害.试验用食用了转基因食品后,到其第三代就绝种了
随着经济的发展、生活水平的提高,人们越来越关注。但是,转基因食品领域的安全性没有引起足够的重视。我国转基因作物的种植面积居世界第4位,排在美国、、加拿大之后,虽然我国已制定了《农业转基因生物安全管理条例》、《农业转基因进口安全管理办法》等相关规定,但处于转型时期的中国经常有较为先进而执行不力的现象,更何况在这方面的制度还做得远远不够。转基因食品的安全问题有其特殊性,因为它较少引起急性中毒而带来轰动效应,而消费者处于弱势地位,局限于知识、财力、时间,不可能深入探讨这个问题,只能依靠现行漏洞百出的食品安全保障体系,捉襟见肘地应对出现的情况与问题。前些年关于转基因水稻的那场讨论,已暴露出某些学者和官员已成为利益集团的代言人。因此,加强转基因食品的安全性研究和控制,切实保障消费者的知情权和选择权是亟待解决的问题
