Filipe Duarte Santos – författare

This book addresses the current challenges of sustainable development, including its social, economic and environmental components. The author argues that we need to develop a new concept of time based on inter-generational solidarity, which focuses both on the long- and the short term. The evolution of man''s notions of time are analyzed from prehistory to modern times, showing how these concepts shape our worldviews, our ecological paradigms and our equilibrium with our planet.  Practical approaches to dealing with the major medium- and long term sustainability challenges of the 21st century are presented and discussed.  

 This is a thought provoking and timely book that addresses the main global socioeconomic and environmental challenges facing the current and future generations, using science-based analysis and perspectives. It presents an historical narrative of the advent of progress, economic growth and technology, and discusses the structural changes needed to co-create sustainable pathways. It provides hope for our future on Earth, mankind’s common home.

 This is an amazing, almost mind-boggling book. The author takes a look at the true whole, i.e., the development of the human enterprise since its very beginning. This enterprise is evidently a possibility under the boundary conditions of cosmological dynamics and natural evolution, but evidently also a highly improbable one. It is all but a miracle that the Earth system in its present form exists and happens to support a technical civilization. Will this civilization last long, will it transform itself into something even more exceptional, or will it perish in disgrace?

Santos dares to address these grandest of all questions, equipped with a unique transdisciplinary wisdom drawing on physics, cybernetics, geology, biology, economics, anthropology, history, and philosophy. And he dares to dive into the deepest abysses of thinking, where categorial monsters like time and progress lurk. Thereby, he takes us on fascinating journey, during which we perceive and grasp things we have never seen and understood before. One of the best essays I have ever read.

This is a wide-ranging and persuasive book written by an undisputed expert. Beginning with a broad history of the Universe, Earth, Life, and Man, it considers the origins and rise of 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 development in the 21st century in the context of global  change. It presents a detailed but non-technical analysis of questions relating to climate change, our dependence on fossil fuels, deforestation, loss of biodiversity, desertification, and air, water, soil, and ocean pollution, as well as problems related to overpopulation, poverty, social and economic inequalities, and conflict potential. The three main, but largely mutually exclusive, discourses on human development and the environment are described and discussed. The main emphasis is on the risks 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.
