The latest bio-technological development, cloning, has driven many ethical issues around the world. An article I found discusses it quite well. There are pros and cons when the cloning is done to animals, and much more when it comes to the idea of human cloning. The first try has been made in September 1993, where Jerry Hall and Dr. Robert Stillman multiplied 17 microscopic human embryos in to 48 to produce the first human clone. Cloning creates the duplication of human/animals that really perform the same capability, personality, complexion, etc. That is a problem to humanity. Even identical twins, that are creature of God, still have differences. There have been long cons to this. If you’re interested about the topic, read here.
