The statement asserts that scientific research should aim at promoting the benefit of the people. Surely this sentiment is shared by many. Throughout history, scientific discoveries are always praised when they solve major problems of the people. From the discovery of penicillin to the electric light bulb, people always remember those who have benefited the greatest number of people. However, scientists do not necessarily have to focus on people’s benefit because environmental problems, disease, energy problems are also our major concerns.

Surely researches attempting to promote people’s benefit have great significance for mankind. One can argue that without medicine, people couldn't live to sixty years; without the electricity people would fear to go out at night; without automobiles people couldn't travel ten miles to visit their friends. The modern discoveries of medicine, electricity and automobiles have transformed our lives.

However, environmental problems are also our major concern. Indeed the industrial revolution and many subsequent technological revolutions have revolutionized our lives, but they revolutionized our environment too, in a different manner. Nuclear waste have caused irrevocable mutations within many species’ bodies; overexploitation of forests have destroyed the natural habitats of many species; oil leak have significantly damaged the sea. The environment deterioration may not have direct impact on human beings, yet it surely will affect people’s long-term development. For example, the distinction of species will affect other species within the same food chain and may result in decrease of food source; The lost of forest due to overexploitation will add to the climatic fluctuation, making winter colder and summer hotter. Therefore, scientists should address to the environmental problems, now more than ever. Many research programs focusing on terrestrial restoration, habitat reconstruction and saving endangered species can greatly promote the environment and biodiversity, and have a long-term benefit for human beings.

Furthermore, biological weapons and nuclear power should also be included in scientific research. Although critics demand vehemently that nations should suspend the research of biological weapons and nuclear power due to the obvious potential threat to human beings, they also have great potential benefits. Biological weapons can be used to destroyed many pathogens, virus and promote our health while nuclear power is likely to solve our energy problems at low cost. Therefore, researches focusing on developing biological pathogen killers and environmental-friendly nuclear energy should be sanctioned, if potential risk can be eliminated by careful experiment and government supervision.

In conclusion, scientific researches should not only focus on people’s benefit, but also on environment problems and even biological weapons and nuclear powers.
