Why should we use cloning?

The goals and purposes for cloning range from making copies of those that have deceased to better engineering the offspring in humans and animals. Cloning could also directly offer a means of curing diseases or a technique that could extend means to acquiring new data for the sciences of embryology and how organisms develop as a whole over time. Currently, the agricultural industry demands nuclear transfer to produce better livestock. Cloning could massively improve the agricultural industry as the technique of nuclear transfer improves. The goal of transgenic livestock is to produce livestock with ideal characteristics for the agricultural industry and to be able to manufacture biological products such as proteins for humans. Researchers can harvest and grow adult cells in large amounts compared to embryos. Scientists can then genetically alter these cells and find which ones did transform and then clone only those cells.

Scientists also ponder the idea of cloning endangered species to increase their population. The possibilities are endless. However, we are actually doing much of this research for the improvement of life for humans. Scientists foresee the cloning of pigs that will produce organs that will not be rejected by humans. Cloning also provides better research capabilities for finding cures to many diseases. There are also possibilities that nuclear transfer could provide benefits to those who would like children. For instance, couples who are infertile, or have genetic disorders, could use cloning to produce a child. Equally important, women who are single could have a child using cloning instead of in-vitro fertilization or artificial insemination. Cloning could also provide a copy of a child for a couple whose child had died.

Why should we not use cloning?

The biggest problem with the use of cloning on a large scale is the decline in genetic diversity. Think about it, if everyone has the same genetic material, what happens if we lose the ability to clone. We would have to resort to natural reproduction, causing us to inbreed, which will cause many problems. Also, if a population of organisms has the same genetic information, then the disease would wipe out the entire population. Helping endangered species by cloning will not help the problem. Currently, zoologists and environmentalists trying to save endangered species are not so much having trouble keeping population numbers up, but not having any animals to breed that are not cousins. The technique of nuclear transfer is also early in its developmental stages. Thus, errors are occurring when scientists carry out the procedure. For instance, it took 277 tries to produce Dolly, and Roslin scientists produced many lambs with abnormalities. If we tried to clone endangered species we could possibly kill the last females integral to the survival of a species. This may be the main reason science is holding out on cloning humans.

Other arguments for cloning include if we are taking nature into our own hands by cloning animals or people. People question when we will draw the line for getting involved in natural events. Religious organizations consider nuclear transfer to cause men to be reproductively obsolete. This claim was deduced by gathering of the information that cloning requires only oocytes, any cell, and a woman to develop in. They also claim that cloning does not respect the fact that humans have souls. They also consider cloning unnatural, and say we are taking the
