This chapter seeks to demonstrate that institutions and NGOs need to interact with children and young people in a way that recognizes them as ‘citizen stakeholders’ now and on behalf of the future. A central tenet of the principle of sustainability includes responsibility for future generations. The principle provides that current generations hold the environment in trust for the benefit of future generations. According to the principle, there exists a moral and ethical obligation to hand over to subsequent generations a stock of environmental wealth, comparable to that which was handed on to us by our forebears.
