As we all know, the world population is rapidly increasing year by year and is also predicted to double in the next 50 years. Ensuring an adequate food supply for this booming population is going to be a major challenge in the years to come. Scientists find that GM foods promise to meet this need and it has been more and more popular not only for the producers but also for the consumers because of its numerous advantages such as pest resistance, lower price, more nutrition and so on. Although it is undeniable that GM food still has some challenges to overcome including environmental hazards, human health risks, influence on food chain of ecosystem and so on, the trend for the development of GM food will not be stopped since these difficulties are quite negligible. In order to have a deep and comprehensive understanding of GM food, let’s firstly focus on what the GM food is. From the definition, the term GM food or GMOs (genetically-modified organisms) is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques. These plants have been modified in the laboratory to enhance desired traits such as increased resistance to herbicides or improved nutritional content. The enhancement of desired traits has traditionally been undertaken through breeding. Genetic engineering, on the other hand, can create plants with the exact desired trait very rapidly and with great accuracy. For example, plant geneticists can isolate a gene responsible for drought tolerance and insert that gene into a different plant. The new genetically-modified plant will gain drought tolerance as well. Not only can genes be transferred from one plant to another, but genes from non-plant organisms also can be used. The best known example of this is the use of B.t. genes in corn and other crops. B.t. crystal protein genes have been
