points: endangered species ethics financial costs food supply medical applications risks
It has past approximately 20 years since Jurassic Park has show up. At that time, the story seemed to be unrealistic. Thanks to development of technology, however, it might be possible to see dinosaurs in zoo. We could reproduce endangered species and organ transplant using cloning techniques. This can seem to be very interesting, amazing and advantageous however, cloning research should be halted for the following reasons: The biggest concern is related to ethics. Clone technology in animals can lead to human cloning. Further, this can be used in the field of organ donation. Instead of waiting for donor, they can utilize their own clone. In this case, cloned human being were generated only for the organ donors. In a movie, it is shown that the counterpart clone of a person was just killed inhumanely for the real person to get his or her organ.
In addition, cloned animals have some risks: high failure rate, aging faster, and causing cancer. In the past they tried to combine the tiger and a lion, which they called a liger but it turns out that it couldn’t live long. According to some researches, scientists show that there are some risks, but they don't figure out the reasons and solutions yet.
Finally, financial costs are considerably great in this field while there are few successes. Only one cloning dog allegedly costs 18 million yen. Even though this could be practical use for human being, still it can be costly. Therefore, availability is limited for the rich people.
For all the above reasons, cloning researches should be ceased although there might be beneficial effects on human being, this technology can change our moral value completely. Therefore we should give careful thought to use it.
