Now it is the least developed world who are not responsible for this climate change phenomenon that bore the brunt of climate change consequences so it is morally and politically correct that the developed world who made this climate change be responsible by providing financial support and technological support to these people.

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.

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.

Our world is one of terrible contradictions. Plenty of food, but one billion people go hungry. Lavish lifestyles for a few, but poverty for too many others. Huge advances in medicine while mothers die every day in childbirth, and children die every day from drinking dirty water. Billions spent on weapons to kill people instead of keeping them safe.

The longer we delay, the more we will pay.

Three decades into this crisis, let us set our sights on achieving the "three zeros" zero new HIV infections, zero discrimination and zero AIDS-related deaths.

The future of any leader or political systems is to be determined by the people of the country.
