In the era of rapid social and technological change leading to more people are curious about the new things, a great number of research are taken into account and we spend a lot of money on it. Whether the money spend on research is valuable, even the results are controversial, the invester should take into account both the negative and positive of the research.
Admittedly, most of the controversial researches are offered some original ideas, and exploring the unknown world play an important role in satistying our appetite for knowledge. Rather than spending money on pursing luxurious life and money, the meaing of doing some reseaches is consipicuous. After all, exploring new things and seeking the way to sovle the problem arrouding us could acceerate the development of the society. For example, a recent report shows that the  ratio of cost in aeronautical business is higer. In the past five years, the average ration of the cost in areonuatical business is 20%, and the recent report indicate that the average ration is 38%. The increasing in cost is almost twince as much as that of five years ago. Athough some research really have some disputs, the reseach also make us better to understand the environment of us and the result of the report shows that most of the people enjoy seeking something new. For exmaple, the research of seeking the extraterrestrial, even though some people think that the existing of the extraterretrial is quixotic, a lot of the derivative ideas to be considered in the process of seeking the extraterrestrial, such us whether exist another planet for human to live, and if it does, the problem of  rare land resource will be solved.
However, even though research has its own value, there are also some negative effects. For instance, the one of the purposes of the human cloning is to help the people do something superior to their abilities, but it is not morally and ethically to human cloning, due to he killing of human embryos, the unsafe process of cloning, and the resulting consequences of having deformed clones. An ethical issue of great importance on cloning is what will be the consequences of it if it was actually successful. Comparing to the value of human cloning, the consequence of devalue human life is more severe. And thus, if we spend a lot of money on human cloning, it's a challenge to against our moral and ethic, which is the basis value of human being. Even it contrubute to making the life convenient, it will not to accepted by the people. So, the research seems not to be a good investment.
Whether the research is a good investment, it depends on the possibiliy of its positive and negative effects . Every research has both of its advantage and disadvantages, considering the leading factors of the result is the most important. In addition, unless assess the feasible of the research, the perspect of the reseach is vagu, it is just likely that spending money on the reseach is waste of the money of tax payer. Instead of taking cost on the reseach directly, we should call for a balance before do some decisions.
In sum,
