Cloning
Cloning, as of recent years, has become a very controversial issue. Society is
firmly divided on the uses and ethics of cloning. Cloning can rang from producing copies
of plants and animals to clones of humans and human organs. But cloning can have
several positive effects for the well being of society.
Cloning plants can have positive effects fo humans. Scientist can clone plants and
alter them to produce healthier food. For example, oranges which contain an abundance
of Vitamin C, can be altered to include Vitamin D and Calcium, which is found amply in
milk. Cloning can also improve the status of hunger-stricken Third World nations. Fruits
and vegetables can be cloned to produce large amounts of food without have to worry
about growing season, climate, or any other environmental factor. They can also be alterd
to be able to be grown in different environments or to produce more food and for a longer
period of time.
Cloning animals can have several ramifications. Foremost, is the benfit of humans.
This can be done in two ways. First, cloning animals can help us understand the way our
cellss divide, multiply and operate. We can also learn how to fix ceratin disorders, thus
leading to tests and research in similar human disorders. For example, sheep have a
disease of the brain, called Scrapie, that causes tremors, loss of motion, and eventually
death. This disease is very similar to the human disease called Parkinson?s disease.
Scientists can try to stimulate new brain cells to divide and regrow damaged areas in the
sheep brain first and then try similar procedures for humans. Animal cloning can also lead
to better production of food. Ranchers can take one cow, the best out of the whole stock,
and clone it. This would improve his sales and our health because we are given a healthier
product. Endangered animals can also benefit from animal cloning. For instance, instead
of doing lab monitored pregnancies and artificial inseminations for endangered animals,
scientists can clone several embryos for the healthiest animal of that species.
Working the way up the evolutionary scale leads eventually to cloning human
organs and ultimately humans. This is the most controversial area of cloning, but despite
the controversy, cloning of human organs and also humans can have some positive effects.
To illustrate, kidney tissue can be used to grow a healthy kidney for patients with frequent
kidney failures. This would prevent donor rejection and also the waiting time for a
suitable donor.
I believe that cloning can be wrong but it depends on the ethics and uses of the
cloning method. For example, cloning animals can be very beneficial to humans in the
knowledge that they learn of the animals of the world and also the knowledge they learn of
themselves. But the uses and ethics are is very controversial. If scientists are cloning to
produce healthier animals and improve the life of humans and the world, then their
intentions are in the right place. But when cloning animals and plants leads to human
cloning then the issue becomes unethical and immoral. To clone a human, many errors
would be made along the way in the production of a normal, healthy human being. And
human clones would have to start as a baby and then grow up. So there would be many
deformed and sick children created along the way of the process of creating a normal
human. Most of them would die in their early stages of development. Humans could also
be cloned in a lower evolutionary form and used as slaves to do hard manual labor. So I
don?t believe that there is any postive results in human cloning. Cloning animals, plants,
and human organs can be beneficial, but again, as long as the intentions are good and in
favor of the improvement of mankind.
