science and technology before moving on to discuss the present state of the world and its our
possible futures. Humans on Earth then addresses the main challenges for social and economic

non-technical analysis of questions relating to climate change our dependence on fossil fuels

conflict potential. The three main but largely mutually exclusive discourses on human

and uncertainties of the short-term future - the next 50 to 100 years - with regard to
environmental degradation and the sustainability of our growth paradigm. ... a sweeping
