Actually, the development of genetically-modified products is a double-edged sword: On the one hand, it contributes to the enhancement of the world crop yield, as well as the quality, and reduction of chemical fertilizer and the pesticide use, helps solution of the famine and undernourishment in developing countries. Besides, it also promotes the development of certain related industries like pharmaceutical and chemical industries; On the other hand, it also brings the unprecedented threat for human beings. We are unaware of the potential effects in human bodies, or any unknown injury to the next generation, caused by genetic modification. Nor can we forecast what kind of influence to the extant gene will emerge.
