The month of June is upon us and as Rio+20, the UN Conference on Sustainable Development, draws nearer, I find myself reflecting on the many great changes the past 20 years have brought, since that first Earth Summit, also in Rio, when the world met to announce a vision for its collective future.

Since then we have seen many more inspiring moments of humanity, when large numbers come together for the common good. It tells us change is possible.
