APPENDIX 381 



A fourth approach would be the sponsorship of a specific sector of problems 

 identified for the carbon cycle. In identifying such a sector, the Institute of 

 Ecology would assess its potential for research clientele and make decisions 

 regarding the feasibility and importance of various research problems. If the 

 Institute of Ecology is principally concerned with biological aspects of the 

 carbon cycle, a focus on the question of whether or not world biomass is 

 expanding or contracting and, in either case, the rate at which this is occurring 

 may be of primary concern. On the other hand, the kind of reasoning Broecker 

 et al. 1 (1971) applied to this question might strip it of its importance with 

 regard to the problem of CO2 increase in the atmosphere. The biological 

 production of trace gases might appear to be more fruitful for the effort 

 involved. Considerable study and discussion by authorities in the various fields 

 represented in this report should be required in order to make a reasonable 

 decision on the application of research effort.
