This paper compares selected analyses of the likely sustainability of society and the factors affecting it, including social, environmental, economic, and political. It examines the likely effects of these factors on South Africa, including possible interactions between them, cumulative effects and feedback loops. The literature increasingly suggests that these effects are likely to be extreme for the South African environment, society and economy, to say nothing of the rest of the world, within the working lives of current or near-future students, i.e. the next forty to fifty years.
