It has been said that knowledge is power. We need to strengthen education systems so that young people can benefit from cultural diversity, and not be victimized by those who exploit differences.

Sustainable development and climate change are two sides of the same coin

Saving our planet, lifting people out of poverty, advancing economic growth – these are one and the same fight.

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.

Too often, they face denial of basic rights such as access to quality health services and education. Such fundamental wrongs have a long and terrible history.

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.

For that to be possible, you have to strengthen your capacity and widen your vision as a global citizen.
