In a world so divided in so many ways, sustainable economic development on a global scale will amount to nothing but a figment of human imagination or, to put it mildly, just wishful thinking. If you agree with this statement, what would you make of the many world summits on sustainable development that have been held over the past 25 years, the latest being the United Nations Sustainability Summit, held in New York on September 25-27, 2017, under the heading "Transforming Our World: The 2030 Agenda for Sustainable Development?" Would it be fair to say that the talks and the agendas for action of past world summits on sustainable development have been, to put it bluntly, "much ado about nothing?" Take a side and discuss your position.
