There are several scientific research activities that are conducted annually globally. These research activities are conducted with the sole aim of solving certain problems that affect human life. Basically, research activities are conducted to improve human life and status of living. Moreover, scientific research findings are used for the benefit of all organisms in the environment. There are different researches that have been conducted in the past using animals. Although most of the research activities have not been successful according to FDA drug assessments, some have led to permanent solutions to some human problems. Animals have been increasingly used for scientific research activities in the recent past, which has led to the increasing debate whether animals should be used for scientific research activities or not. Considering factors such as past results, animal rights, and human responsibility to animals among others, animals should be used for scientific research. United States conducts the highest number of scientific research in the globe. Moreover, millions of animals are used for scientific research activities in the United States. Animals are mainly used as models during scientific research activities. Scientists prefer using animals as models in medical and biological research activities to enhance better understanding of human development, injury, physiology, anatomy and diseases among others. United States is among the states in the globe that has produced lasting solutions to human suffering due to the research activities that they conduct. Furthermore, there are several drugs, which treat diseases that were considered international crisis due to testing of the sample products on animals. Moreover, several drugs have been improved through research activities and use of animals in research. Human life has been improved, and diseases eradicated or controlled through the use of animals in scientific research. Therefore, considering the benefits that have been accrued from research activities due to use of animals in scientific research, I support that animals should be used in scientific research (Carruthers 132). The environment must be protected according to the United Nations Environmental Program. There are several components that make up the environment. All the components need each other in one way or the other for survival. However, they must be preserved for the eco-system to balance. This has led to the establishment of several bodies and organizations that advocate for the rights of animals, plants and human among other components of the environment. Animals’ right to live must be respected. Using animals in scientific research may be opposed that the rights of animals are abused. However, animals use in scientific research saves the life of other organisms in the eco-system, which has led to the balance in the eco-system. Their use in scientific research is not in vain, but beneficial in saving lives of millions of human beings, who could have died due to diseases in case research activities were not conducted. Therefore, since using animals for scientific research has saved lives of millions of human beings, I agree that animals should be used
