英文文献摘要：
During this past year those of us who work at Resources for the Future were stimulated by our external Research Advisory Committee to identify the most important problems that will face our society in the next 25 years. Even though no attempt was made to select problems that ..were amenable to research, it was hoped that out of this would perhaps come new research efforts that would be of greater significance.
