Scientists also ponder the idea of cloning endangered species to increase their population. The possibilities are endless. However, we are actually doing much of this research for the improvement of life for humans. Scientists foresee the cloning of pigs that will produce organs that will not be rejected by humans. Also, as mentioned earlier, livestock can produce biological proteins helping people who have diseases including diabetes, Parkinson's, and Cystic Fibrosis.
Cloning also provides better research capabilities for finding cures to many diseases.
There are also possibilities that nuclear transfer could provide benefits to those who would like children. For instance, couples who are infertile, or have genetic disorders, could use cloning to produce a child. Equally important, women who are single could have a child using cloning instead of in-vitro fertilization or artificial insemination. Nuclear transfer could also provide children who need organ transplants to have a clone born to donate organs. Cloning could also provide a copy of a child for a couple whose child had died.
