CLONING EXTINCT SPECIES.

Many species become extinct each day. Despite increasing interest in using cloning to rescue endangered species, successful interspecies nuclear transfer has not been previously described, and only a few reports of in vitro embryo formation exist. There are also contradicting views on the idea of cloning where some view it as good and some are against it. Extinction threatens the life of birds, mammals and plants yearly. With this trend, the rare species of vertebrates will soon be lost despite the efforts put in maintaining their bio diversity through habitat and wildlife conservation.

To start, cloning ensures the continuity of species. After scientist clone a DNA from a living being, the species will continue to exist. It should be understood that recently, scientists have not only cloned other species, but they have advanced the science of cloning to now include genetic modifications that serve particular pharmaceutical or agricultural purposes. One type of modification is the production of transgenic animals that have genetic material from another species spliced into their genome. For example, sheep have been engineered to secrete a human protein, which makes human protein available for different purposes. Also, I find cloning something that the 21st generation needs since after cloning, there is the production of genetically modified animal organs engineered to be compatible with a human recipient.

In conclusion, many effects of cloning mammoths are based on assumptions. On one hand, the potential harms and long-term effects seem more certain than the potential benefits if the clones are reintroduced into the wild and harm other species. However, these harms can be avoided if restrictions are placed on mammoth cloning to minimize negative impacts and maximize benefits.
