Answer

I write the answer for my question 1 " What advantages does the cloning might have?". First, stem cells will eventually change the face of medicine as we know it. Given the fact that the cells can be manipulated to mimic other types of cells, this can provide new ways to treat diseases like cancer and Alzheimer’s. And secondly, cloning can reverse the effect of aging. However, I think people of advanced age would increase and progress an aging society. Thirdly, there are so many dangered species in the world, but cloning may be able to protect them in future.
