  -- the demographic dimension. Global and local populations at present and in historical times; future projections

  -- fluxes. Sources, pathways and sinks of energy and materials used; stability and instability of these sources, pathways and sinks

  -- the technology dimension. The scopes for constructive and destructive use of technologies

  to render the above, very wide scope more manageable by developing interaction, where possible, with other SGR members and study groups with relevant interests and expertise. These exist in, for example, environment (especially climate change), energy, biotechnology, education (Science Matters project) 

  to make clear, in all reporting, what are the assumptions underlying analyses and conclusions. To pay special attention to the sensitive nature of the subject and to address difficult and controversial questions with respect for others' sensibilities but not to be pressured into silence
