转基因——一个看似离我们遥远的名字,但是,它已经悄悄地潜入我们的生活,来得令我们措手不及。而转基因生物双重性的现实也让我们看到了它“利”与“弊”之间的强烈反差。转基因生物的高产的确给农业、医学、工业等多个领域带来了重大的经济效益,但其污染也同时给人类的健康和生态环境带来了不可忽视的负面影响。何为转基因生物:转基因生物是利用分子生物学技术,把某些生物的基因转移到其他物种中,改造生物的遗传物质,从而使其形状、营养品质、消费品质等发生转变。迄今为止,世界转基因生物已达120种左右。从其性能上区别可分四类:一是可抵御害虫侵害,
Transgenic - a seemingly distant name from us, but it has quietly sneaked into our lives, too much to get us caught off guard. The reality of the duality of GMOs also shows us the strong contrast between its “benefits” and “disadvantages.” The high yield of genetically modified organisms does bring significant economic benefits to many fields such as agriculture, medicine and industry, but its pollution also brings negative impacts on human health and environment. What is a GMO? GMOs make use of molecular biology techniques to transfer the genes of certain organisms into other species and transform the genetic material of the organisms so as to change their shape, nutritional quality and consumer quality. So far, the world has reached 120 kinds of GMOs. From its performance can be divided into four categories: First, to resist pests,
