Cloning is a controversial issue. Some people are ready to eat cloned fruits and vegetables, but many people are against cloning animals. They think it is morally unacceptable. The question of human cloning is even more controversial.
Suppose we cloned a man. Are we really sure he will be a man? Who will be responsible for him? Who will bring him up? Will he be happy? Will he have the same rights as we have? What would happen if a dictator, someone like Hitler, cloned himself? Would we be able to survive?
Cloning animals opens exciting medical possibilities.  Many people are in need of tissues  and organs for transplantation. But it isn’t easy to get such organs as, for example, heart, liver or kidneys. Cloning can solve this problem. Many animals are on the brink of extinction. Cloning can be used to preserve them. Besides, scientists can create animals which produce more milk, meat and wool, or animals which don’t catch certain diseases. This can save the lives of starving people.
The growing scientific field known as regenerative medicine, also known as therapeutic cloning, allows thousands of lives to be saved from cloning human cells, tissues, and even organs. Cloning human body parts guarantees a genetic match to prevent organ rejections and also does not require immunosuppressive drugs. However, this research is still in its infancy and requires a lot more time, effort, and money before it matures into saving a lot more people. If human cloning is completely banned, then this type of research would be stopped and a lot of lives would be lost. Cloning could be used to replace family members who have died in accidents
But there are uncertain genetic consequences: many of the early animal clones had clinical problems derived from genetic effects. For example, old age illnesses in the youth. Human cloning is the creation of a genetically identical copy of an existing or previously existing human. The term is generally used to refer to artificial human cloning; human clones in the form of identical twins are commonplace, with their cloning occurring during the natural process of reproduction. There are two commonly discussed types of human cloning: therapeutic cloning and reproductive cloning. Therapeutic cloning involves cloning adult cells for use in medicine and is an active area of research. Reproductive cloning would involve making cloned humans.
Some people argue that the research should go on because any research speeds up progress. Only through progress people can find how to treat different diseases using cloned embryos for that purpose. It will allow us to study and treat different diseases, but the embryos could one day become cloned children and this is dangerous. It can lead to a mass creation of clones. Those clones may be used in war as it happened in one very famous movie called “Star Wars».
 Many people argue that the research of cloning will allow sick people to have a real chance to obtain cloned organs when necessary. I agree that it will allow sick people to receive their cloned organs for transplantation, thus lessening their pain, but embryos that are used for cloning organs will be used as material, not as living organisms. We should not forget that we are human beings that have moral values. Once everyone of us started as an embryo. Now we are alive, not destroyed. Who made a decision to save our lives?” We are human beings, not material for research. We cannot be cloned. Only God can create us and take our lives. We must stop the research of cloning.  It may lead us to unpredictable future.
Are you for or against cloning? Prove your point of view.

Every year hundreds of scientific discoveries are introduced in industry, agriculture, medicine, education & service. New inventions are appearing every day to make our lives easier, longer, warmer, speedier & so on. The development of science has increased man’s knowledge of nature so greatly that now it influences all sides of human life. All these achievements were absolutely impossible without inventions & discoveries made in different fields of science & engineering by great scientists: mathematicians, physicists, chemists, biologists, linguists, historians, etc.  Read about some of them here.
Whose contribution is the greatest? Why?
