Many people, however, are unwilling to accept the possibilities genetic research allows.For example, one reason some women do not use the largest genetic testing for breast cancer is because they are afraid they will be discriminated against.Another problem is that many people do not want to discover their weakness.What if they learn that they have a disease for which there are no medical cures? How will such knowledge affect their lives? Do people really want to know what they will die of?

Many people believe that history has not always shown human decisionmaking to be bright when it comes to ethical (道德的) choices.Jeremy Rifkin is probably the most well known opponent of genetic engineering.He believes that humans are not responsible enough to experiment with genes and should not “play God”. He asks, “Just because it can be done, does that mean it should be done?” He points out that our society will eventually look and act the same if parents select the traits of their children, and he questions the desirability of such a society.

One of the fears expressed about genetic experimentation involves privacy.Already blood sample taken from patients in hospitals have been used for genetic research without the patients’ permission. Most people would agree that one’s health and genetic makeup are private concerns.But if insurance companies gain access to this information, it could have a large impact on insurance coverage or costs; if employers gain access to the information, it could have a large impact on hiring or promotion decisions.The possibilities for discrimination are obvious.
