In her article Fran Baum is correct in pointing out that the political complexities of our globalised world must be taken into account by public health professionals.1 Global health futures are directly or indirectly associated with the transnational economic, social, and technological changes taking place in the world.

Therefore, rather than expanding the list of “global bads” associated with global interconnectedness, many of which have been enumerated in Baum's analysis, we shall try to tip the balance somewhat by mentioning some of the under-utilised opportunities associated with global change. In this vein, we will briefly mention three perceived opportunities.
