Some facets of that transition are already evident; others are only beginning to be understood. One stems from the impact of the demographic momentum now experienced by the world, which is not expected to stabilize until well into the middle of the next century.

Here the concerns range from such global issues as atmospheric accumulation of carbon dioxide and the effects of acid precipitation, to the degradation of local environments, such as the depletion of soils, forests, sources of fresh water and non-commercial fuels. 30. But the issue to which Governments are likely to pay closest attention, because it will most directly affect their daily concerns, is the transformation now under way in the world's industrial and financial structure.
