Do You Want To Be Cloned?

Is cloning a good thing for society? Cloning is the process of duplicating biological material. There are three types of cloning technologies; recombinant DNA technology, reproductive cloning, and therapeutic cloning. Recombinant DNA technology is when a DNA fragment of interest is transferred from one organism to a self replicating genetic element like bacteria. Reproductive cloning is when an animal is made that has the same nuclear DNA as another animal. Therapeutic cloning is the production of human embryos for use in research. There are many arguments that are for and against the science of cloning.
There are many reasons why cloning can be a good thing for society. Gene therapy is used to treat certain genetic conditions. Food crops are genetically engineered to improve taste and nutritional value, and to resist certain types of diseases. Reproductive cloning is used to repopulate endangered animals or animals that are difficult to breed. Therapeutic cloning may be used to produce whole organs from single cells in humans, and to produce healthy cells to replace damaged ones in degenerative diseases.
There are also many reasons why cloning may be a bad thing for society. Reproductive cloning is expensive and very inefficient. Cloned animals have more compromised immune function and higher rate of infection, tumor growth, and other disorders. Many of the cloned animals have not lived long enough to create good data about how clones age. Many feel that human cloning is unethical because of the lack of understanding about reproductive cloning, we are not sure how cloning may impact mental development. The amount of unknown variables makes attempting to clone humans potentially dangerous and therefore ethically irresponsible.
There are both good and bad things about cloning. Cloning can be used to treat genetic conditions, repopulate certain species of animals, and may be used to produce human organs for transplant. These reasons make cloning a wonderful thing for society. There are also many reasons why cloning is not good for society. Cloning is expensive, inefficient, and clones have shown more developmental problems than normal. These reasons cause people to feel that cloning is unethical.
I feel that if there cloned animals that live longer allowing more studies and observations to be made cloning will do some amazing things in the future. If there is not success with cloning in the near future I feel that the unknown will scare society too much and cloning will be outlawed.
