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.

Today, we have more than 110,000 men and women deployed in conflict zones around the world. They come from nearly 120 countries ... Thanks to their efforts, life-saving humanitarian assistance can be delivered and economic development can begin.

I spend most of my time in South Korea but at least one-third of my time is spent traveling around the world, meeting people, speaking about climate change and sustainable development and trying to foster global citizenship especially for young people. What I observe is there clearly is a need for global citizenship. That is exactly right. We are having troubles around the world. We need global vision.

Climate change is destroying our path to sustainability. Ours is a world of looming challenges and increasingly limited resources. Sustainable development offers the best chance to adjust our course.

From the Balkans to Africa, from Asia to the Middle East, we have witnessed the weakening or absence of effective governance leading to the ravaging of human rights and the abandonment of longstanding humanitarian principles. We need competent and responsible states to meet the needs of "we the peoples" for whom the UN was created. And the world's peoples will not be fully served unless peace, development and human rights, the three pillars of the UN, are advanced together with equal vigour.

I call on men and boys everywhere to join us. Violence against women and girls will not be eradicated until all of us - men and boys - refuse to tolerate it.

The world is over-armed and peace is under-funded.
