What are those of us who have chosen careers in science and engineering able to do about our current problems First, we can help destroy the false impression that science and engineering have caused the current world trouble. On the contrary, science and engineering have made vast contributions to better living for more people. Second, we can identify the many areas in which science and technology, more considerably used, can be of great service in the future than in the past to improve the quality of life. While we can make many speeches, and pass many laws, the quality of our environment will be improved only through better knowledge and better application of that knowledge. Third, we can recognize that much of the dissatisfaction we suffer today results from our very successes of former years. We have been so greatly successful in attaining material goals that we are deeply dissatisfied that we cannot attain other goals more rapidly. We have achieved a better life for most people, but we are unhappy that we have not spread it to all people. We have reduced many sources of environmental disasters, but we are unhappy that we have not conquered all of them. It is our raised expectations rather than our failures which now cause our distress. Granted that many of our current problems must be cured more by social, political, and economic instruments than science and technology, yet science and technology must still be the tools to make further advances in such things as clean air, clean water, better transportation, better medical care, more adequate welfare programs, purer food, conservation resources, and many other areas. According to the author, to improve the quality of environment, it is important to ______.

A. call on the public to action
B. pass related law
C. eliminate the destructive effect of science and technology
D. use better knowledge of science and technology
