Using genetic technology to revive species that are in danger of extinction is an impressive yet complicated effort combing cloning and genetic modification.
One striking example is the case of the black footed ferret. Although considered to be extinct, scientists have managed to revive it using DNA from dead specimens. Another successful attempt was the work done to save the white rhino. Because only two females have remained-after the death of the last male in a reserve in Kenya- geneticists have preserved cells and are trying to create embryos from them.
Even so, all the above raise ethical issues concerning the control of genetic material and the possible negative effects on the environment. In addition, these methods cost a lot and are very complex, a fact that hinders their worldwide use. It is also vital to deal with the causes of extinction, such as the loss of habitat and illegal hunting in order to protect endangered animals.
In spite of all these matters of interest , genetic technology can surely offer solutions and help protect easily hurt species if used wisely for both animals and the planet.
