Hello. It's me again

Could you read my essay and tell me if it correct or correct my mistkes.
Thank you an advance.
Science is developing very fast and nowadays scientists have already succeeded in cloning. People have different attitude to it. Some of them believe that cloning industry must be controlled by the government but others do not think so. Now I would like to express my point of view on this problem.
I consider that the government should oversee human cloning research. First of all, these experiments are not safe enough and seem to be dangerous. There is a big risk of abnormal effects. What is more, scientists do not know how clones will behave and what kind of being they will be.
However, scientists claim that human cloning is absolutely safe and there is no necessity for governments to control it. They state that cloning gives people new medical possibilities. We can use clones to create organs for transplantations or duplicate someone who was loved and died.
In addition, human cloning will change our ideas about the value of a human life as we might switch from having children to manufacturing them and the results of this action can be unpredictable.
In conclusion, this issue is far from solving yet, but I am sure that human cloning must be under strict control of the government because one wrong action can lead to disaster.
