We have all heard of the web of life. The way we live threatens to trap us in a web of death.

On this International Day for the Abolition of Slavery let us reaffirm the inherent dignity of all men, women and children. And let us redouble our efforts to build societies in which slavery truly is a term for the history books.

Sustainable development is the pathway to the future we want for all. It offers a framework to generate economic growth, achieve social justice, exercise environmental stewardship and strengthen governance.

I call for the need of world leaders to address climate change and reduce the increasing risk of disasters- and world leaders must include mayors, townships and community leaders.

You have to work and think about how we can make this world a better place for all. This is what I'd really like to ask our young leaders. We will try as leaders of today to minimise the problems which we will hand over to you. But it is to you. You have to take ownership and leadership of tomorrow. For that to be possible, you have to strengthen your capacity and widen your vision as a global citizen.

We hold the future in our hands, together, we must ensure that our grandchildren will not have to ask why we failed to do the right thing, and let them suffer the consequences.
