Bioethics, we all know what it means even if vaguely. Despite the name, it's a humanistic scientific area that I personally describe as the consciousness of the biotechnological progress. Bioethics allows us to observe science from another perspective, a humanitarian perspective and preserving the biosphere around us. Through bioethics it’s possible to advance in the field of biology and biotechnology without harming our study objects, living beings, because all the science that deals with something so important and yet so little known as life itself has to balance the pros and cons with regard to possible consequences of this manipulation by the man. And it is this lack of knowledge that makes bioethics so important because if we still know so little about life and living things , it can be considered to irresponsible act invasively on such study objects because you can not predict the outcome and its consequences . We all know that, more than any partition of nature, the biosphere is strongly linked by physical and chemical processes: Among ecosystems, among populations and even between species, these interactions are essential to the balance of the nature itself. With the possibility to manipulate living organisms at a genetic level, bioethical issues gained great recognition by the scientific community. To what extent is our right to manipulate information, the "instruction manual" so to speak, which leads to life, and that sets living beings as we know them in nature. From another perspective: The human being is part of the biosphere there are about two hundred thousand years over the last century scientific discoveries revolutionized the world, we have the example of the discovery of antibiotics but then we can not forget the atomic bomb crippled a part of land area and killed thousands of people. In a hundred years this was the scale of the impact caused by technological advancement. Now a living being that is part of the biosphere, two hundred thousand years old and that in a hundred years affected the planet irreversibly, begins to manipulate the information itself that defines life itself. How amazing and scary at the same time is this reality? To what extent is our right to do it? What are the consequences impossible to be predicted right now? How is this knowledge going to be used in the next hundred years? And in the next thousand years? Bioethics makes sure that when we find out the answer to this questions, we will be prospering not doomed.
