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, let us promise to make peace not just a priority, but a passion. Let us pledge to do more, wherever we are in whatever way we can, to make every day a day of peace.

The basic building block of peace and security for all peoples is economic and social security, anchored in sustainable development. It is a key to all problems. Why? Because it allows us to address all the great issues-poverty, climate, environment and political stability-as parts of the whole.

Terrorism is a significant threat to peace and security, prosperity and people.

Climate change does not respect border; it does not respect who you are - rich and poor, small and big. Therefore, this is what we call global challenges, which require global solidarity.

National boundaries these days are not that important because of transformative technological development. Now we are talking about the fourth industrial revolution.

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.
