"Cloning represents a very clear, powerful, and immediate example in which we are in danger of turning procreation into manufacture" said Leon Kass. Cloning is very controversial topic in the world today. Some say cloning is playing God and some say cloning is correcting our mistakes. Whatever you may think scientist all over the world are studying the affects of cloning. Some of the most divisive talks of cloning are over the cloning of endangered species and cloning animals for consumption. This paper will review the each these topics in further detail. Animal cloning is a fairly recent scientific advancement that's been on the radar since about 1996. Genetic engineers have developed a method that can be used to prevent the extinction of endangered species. Although it sounds complicated, the procedure is quite easy to understand. First the scientists obtain cells of one of the few remaining animals of the desired endanger species. Tissue samples from each of the animal are stored in vials, which are submerged and frozen in liquid nitrogen. The cell nuclei containing DNA are inserted into unfertilized eggs that have been extracted from a member of the species to be cloned. The eggs are then fused with the cells containing the DNA. Each egg-cell fusion eventually develops into an embryo. The resulting embryos are implanted in another animal from the desired endangered species, who acts as the surrogate mother. The surrogate mother then births the desired genetically identical replicas of the animal from which the DNA-containing cells were obtained. While animal cloning may have a role in the preservation of endangered species, it cannot conquer extinction on its own. It's important to think about what caused the deterioration of a species in the first place, we have to consider the root of this devastating problem. Animal cloning is a band-aid solution to mass extinction...
