Animal Cloning Cloning has been a controversial issue ever since 1996 when scientists cloned the first mammal. The term “cloning” means to process or create identical genetic copies of an organism. Cloning is a complex issue that attracts a wide range of opinions. Although, most Canadians think that even though cloning can be beneficial, it is still wrong and dangerous because it’s unethical, its costly and most importantly, it concerns with health and safety issues.

Cloning is a very costly process and much of the money ends up going to waste because ninety-five percent of the time cloning attempts fails. Even the five percent of the animals that do succeed, some turn out to be unhealthy. A significant number of cloned animals, as well as surrogate mothers who carry clone pregnancies, suffer serious and painful diseases and deformities to produce each successful cloned animal. With such low success rates, not only do the cloned animals endure suffering, but so do hundreds of additional animals as they are pumped with hormones and their eggs harvested, or as they are implanted with embryos, often repeatedly, in an attempt to produce just one cloned animal which survives.

In 1996, Dolly the sheep was the first successful cloned mammal created by Ian Wilmut. Dolly only lived up to six years, which is half the life of a regular sheep. Some people claim her life was shorter than normal because she was a cloned animal, while others argue that her death was completely natural. There is little rigorous scientific data available to make any claims about the health of the cloned animals, but the few studies that have been done indicate that these animals are weaker and less likely to survive than their conventional counterparts.

For cloning a mammal such as a sheep like Dolly, scientists remove the cell nucleus of an egg from a female sheep, then a cell from an adult...
