Are the statements in

(a) and

(b) below saying the same thing? (Hint: think about the tradeoffs between concerns of intra- and intergenerational equity.)

(a) Sustainability is principally about intergenerational equity.

(b) ‘Sustainability is not exclusively or even primarily an environmental issue. It is fundamentally about how we choose to live our lives, with an awareness that everything we do has consequences for the 7 billion of us here today, as well as for the billions more who will follow, for centuries’ (from the foreword section of the Human Development Report 2011: Sustainability and Equity, a Better Future for All).
