Cloning is a method by which a stem cell can be grown into a desired organ in general. Since the birth of dolly the sheep in 1996 scientist have managed to clone about a 20 different species including cats, goats and sheep. Now they are taking a step which is more contravention that is cloning a human. Human cloning has been accepted by a very few scientist only others refuse to do so and this has been summarized below.

Many of us think that cloning is a complete Xerox copy of the original species. But this is not true. In fact cloning is developing of stem cells which are of embryonic origin and can specialize into any tissue such as heart , brain ,liver etc. the practice of human cloning is achieved by taking an un nucleated egg cell from the species and inserting an somatic cell taken from the skin and fusing these cells together gives a cell with 2n nucleus. Here the somatic cell taken from the skin acts as an software and the un nucleated egg cell acts a hardware. This method is carried out in a highly specialized laboratory with suitable condition.

The goal of this research is nothing to do with cloning. Cloning is just a tool. The idea of this research is to create fresh tissue in laboratory. For example someone is in heart attack and you are scaring inside you could use fresh tissue made in the lab to treat scaring. If one has a nerve aliment like a alzimer disease you could transplant lab made tissue and hopefully you can solve this problem. Thus the fleashy got organs from the stem cells thus help in organ replacement of the defective organs. If this procedure is widely accepted then there would be no problems for the donors for the organs.

Only a very few scientist are willing to continue with the human cloning. Most of the scientists have regretted to clone a human because of two main reasons they are as follow
It is non-ethical and it is against to nature
Generally they refuse for human cloning because iit is banned in many of the countries
It is incredibly controversial and it will provoke a huge outcry scientist have been cloning a variety of species but human cloning is not yet in practice because of many financial, ethical and against the laws of nature.

There are many difficulties in human cloning they are
Scientist have no head progress in cloning a monkey or an ape which is a close related to human in its genetic code
Primates such as humans have a egg cell which is more fragile than other species. Scientist fear that if cloning occurs there would be a wastage of eggs.

The success percentage of the clones would be one in forty chances of survival.

The cloned species of cats have developed anemia therefore this may lead to genitival diseases in the cloned species
It could take a hundred or more tries to make a human egg cell enucleated and insert a somatic cell into it. A bucket of hundred ovaries can produce about 1000 eggs thus finding a donor for egg is not that easy. This process may take up to an expense of $35,000 so it cannot make a successful clone.

These cloned cells may be mutated and cause severe issues.

Some of them argue that the technologies for cloning an human has not yet developed banned strict laws may be on one side but on the other side there are some of the moral and ethical concern that stops human cloning some of them are as follow.

If a human is cloned from a single paren
