Jeffrey Sachs is teaching a free online course called 'The Age of Sustainable Development.' The course starts in September and goes through the beginning of December.

Course Description:
This course provides an introduction to the interdisciplinary field of sustainable development, drawing on the most recent developments in the social, policy, and physical sciences. Sustainable development is the most urgent challenge facing humanity. The fundamental question is how the world economy can continue to develop in a way that is socially inclusive and environmentally sustainable. The course describes the complex interactions between the world economy and the Earth’s physical environment. Ecological processes and constraints (climate, disease ecology, physical resources such as soils and energy sources, topography and transport conditions) significantly shape the patterns of economic development, demography, and wealth and poverty. At the same time, human activities (farming, land use, urbanization, demographic change, and energy use) change the physical environments, increasingly in dangerous ways. The course offers a broad overview of the key challenges and potential solutions to achieve sustainable development in the 21st century.
