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.

Freedom is a timeless value. The United Nations Charter calls for encouraging respect for fundamental freedoms. The Universal Declaration of Human Rights mentions freedom more than twenty times. All countries have committed to protecting individual freedoms on paper - but in practice, too many break their pledge.

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.

We have reached a new milestone as a human family. With seven billion of us now inhabiting our planet, it is time to ask some fundamental questions. How can we provide a dignified life for ourselves and future generations while preserving and protecting the global commons - the atmosphere, the oceans and the ecosystems that support us?

Women hold up more than half the sky and represent much of the world's unrealized potential. They are the educators. They raise the children. They hold families together and increasingly drive economies. They are natural leaders. We need their full engagement... in government, business and civil society.

We have a legal and moral obligation to rid our world of nuclear tests and nuclear weapons. When we put an end to nuclear tests, we get closer to eliminating all nuclear weapons. A world free of nuclear weapons will be safer and more prosperous.
