Cloning is the process of making an exact copy of a plant or animal and developing it either naturally or artificially. An example of natural cloning is identical twins, who are produced from the same egg. On one hand, some people think cloning can help save research time, reduce the number of animals required for testing, produce more accurate results, and lead to more effective treatments. On the other hand, others are opposed to cloning being used in our life and they worry about the ethical questions it raises. As far as I am concerned, cloning is a powerful instrument. Whether it is a blessing or a curse to mankind depends on mankind instead of cloning.
