World Bank launches Responsible Growth for the New Millennium

By the year 2050, world income will reach more than $135 trillion, up from $35 trillion today, according to the World Bank’s new book “Responsible Growth for the New Millennium: Integrating Society, Ecology and the Economy”. The book suggests that 2050 could be the time when the dream of a world free of poverty becomes a reality, or it could represent a time of global uncertainty, social unrest, and environmental degradation.

The world of 2050 will have more than 65 percent of the population in urban areas. The infrastructure and housing needs, if city dwellers are to enjoy healthy and productive lives, will increase dramatically. But, according to the book this also presents a great opportunity. With most of these investments still to be designed, they could contribute to environmentally sustainable urban environments.
