With a world population of seven billion people and increasingly limited natural resources, the imperative of living sustainably so as to ensure the prosperity of future generations has become increasingly salient. It is for this reason that the central aim of ESD is to encourage young people to become responsible citizens of the future. This notion was the crux of Chapter 36 of Agenda 21, published by the United Nations Conference onEnvironment and Development in Rio de Janeiro,Brazil, in 1992. This document outlined the need to educate the world’s citizens so that broader sustainability goals would be met by the actions of an embracing general public and stated the following goals for the program: “By 2030 ,ensure that all learners acquire the knowledge and skills needed to promote sustainable development, including, among others, through education for sustainable development and sustainable life-styles, human rights, gender equality, promotion of a culture of peace and non-violence, global citizenship and appreciation of cultural diversity and of culture’s contribution to sustainable development”(UNCED 1992).
