Human activity overuses the resources of the planet at a rate that will severely compromise the ability of future generations to meet their needs. Changes toward sustainability need to begin within the first decade of the 21st century or environmental deterioration will become irreversible. Thus the need to develop a mindset of sustainable development - the ability of society to meet its needs without permanently compromising the earth’s resources - is pressing. This text clarifies the meaning of sustainable development and describes the conditions necessary for it to occur. With contributions from an international team of policy shapers and makers, the book should be a useful reference for environmental, developmental, social and organizational psychologists, in addition to other social scientists concerned with the impact current human activity will have on the prospects of future generations.
