Figure 5.6 illustrates how the six above-mentioned scenarios fall along a spectrum, ranging from positive to negative growth outcomes. The (dark blue) colour indicates the desirable scenarios, the (light blue) may be considered second best options, and (white) indicates the non-desirable scenarios. Although it is important to understand the extent to which growth occurs in sectors specifically aimed at promoting environmental protection or resource-conservation services or technology, these sectors generally represent a relatively small subset of the larger service and manufacturing economy in a region.
