SHOULD THERE BE ANY LIMITS TO SCIENTIFIC RESEARCH?

INTRODUCTION

In the last few years, science has reached tremendous results, incredibly helping mankind in many fields of everyday life. Today, everyone knows that science is the base for modern technology- new materials, tools, techniques and power sources make our life more comfortable and easier.

However, at the same time, science has also been able to create new objects and inventions that have had a very strong negative impact on human history.

Therefore, our question is as follows: is it right not to affect and bias science or is it necessary to set any limits to scientific development? 

FIRST PARAGRAPH

In the first place, it is obvious that our life has benefited greatly from scientific progress.

The main positive aspects can be found in medical research, in fact, thanks to science today we have discovered how to cure certain diseases and we have created machines and electronic devices  helping human beings at work.

Without science, we would not have any kind of penicillin, we would not have any blood transfusions or we could not treat any types of cancer.

Likewise, without science we could not travel so often and fast- buses, trains, planes have changed our way to move at long distances in a dramatic way.

What's more, can we imagine our life without a computer, a smartphone  or the Internet? They are  key elements for all of our activities. From this point of view, it seems to be all peaches and cream. How could we suppose  that scientific research may have any limits?

SECOND PARAGRAPH

However, not all scientific research may be considered positive. Without scientific progress, the nuclear bomb would not exist, If we consider that aspect, we realize that because of the discoveries applied to military conflicts, science has caused the death of millions of people. The creation of drones has also recently raised  moral questions- they may be used in a wide range of civilian roles for helping people in need, for example  for search and rescue, but they may be used for military reasons, as well.
Besides, more and more people are constantly being replaced by robots working faster and not requiring any wage. Conspiracy theories have been figured out by some people who think that one day in the future, robots will be so intelligent that they will be able to dominate human beings.
In addition, science is criticized for being immoral, above all regarding all those studies and research related to human integrity, such as human cloning. Many people are in fact afraid of genetic modification.

THIRD PARAGRAPH

Due to cloning it is nowadays possible to make beings having some characteristics to the giver of the stem cells. With regard to this aspect, science has now so advanced that living robots have been lately invented. These machines, called xenobots, are  made from frog stem cell and will be  able to do lots of things by their own, for example releasing medicines in the body. In my view, some limits are necessary to avoid  the abuse that may be done through science. Cloning and artificial intelligence are not bad in themselves, but they could if they are used carelessly, for disreputable, immoral aims. The limits should be given by ethics, a set of moral obligations that establish what is right and what is wrong. Some ethical standards should guide scientific research and ensure that it is carried out by respecting the rights of all human beings and animal subjects, by complying with the environment, not providing any harm and bad effects to human life or causing  disasters everywhere in the world.

CONCLUSION

To sum up, every day we are totally immersed in the effects of science, we can travel, we can socialize, we can study, we can cook, we can work, we can do whatever we want, thanks to science. However, science has also given us the potential for nuclear holocaust and the destruction of the environment through overpopulation and consumerism, as well.

Science is a tool meant to serve us but it may become a thing serving itself instead. It is highly recommended that it is in the right and good hands. Science is progress and improvement but only if it is used providing benefits to all human beings and not only to some of them, always being aware of the possible negative results associated with new scientific inventions.
