Genetic engineering is the concept of taking genes and segments of DNA from one individual or species (e.g., a spider) and inserting them into another individual or species (e.g., a goat). The biotechnology of genetic engineering has created a broad spectrum of ethical issues, ranging from genetically modified organisms, as in crops, to animal and human cloning, genetic screening for diseases, prenatal and preim-plantation diagnosis of human embryos, xenotrans-plantation, and gene replacement therapy. Genetic engineering presents an exciting range of possibilities. For example, genetic engineering can give plants and crops desirable traits, such as drought resistance and additional nutrients. Such promises are not without their potential perils; some environmental groups raise concerns that the creation and use of these genetically engineered plants amounts to “genetic pollution” and that they should not be released into ...
