This section reviews the many agencies which are creating change. As there are many of these, this is the largest section of this web site. We offer five major topic headings, as shown below. Most of these have many sub-headings, individually pointers to other sources of information.
|Growing connectivity and its implications.|
|The implications of social and demographic change.|
|Knowledge and technical capabilities.|
|Natural systems and human impact.|
