During my nearly five years as director-general of WHO high-level policymakers have increasingly recognized that health is central to sustainable development.

Thanks to evolution our bodies have powerful ways to ward off illness and infection and enable us to live long and healthy lives. Why then do health costs continue to climb at unsustainable and frightening rates?

A world in which government is burdened by historic debt philanthropy has limited resources and the private sector is only interested in its own personal gain is simply unsustainable.

We have a government that borrows $4 billion a day. We have a government that owes trillions of dollars in debt half of that to foreigners most of that to Chinese investors. I don't - that is extreme. Not only is it extreme. It's insane and it's unsustainable.

God is even though the whole world deny him. Truth stands even if there be no public support. It is self-sustained.

If we are to garner sustained U.S. domestic support for future trade agreements we have to make sure those Americans who have suffered as a consequence of past agreements have an effective social safety net adjustment assistance opportunities for retraining and new job creation that enables all Americans to thrive.

I really hope that we'll have a sustainable future on this planet I really do. So I probably geek out mostly about learning more about how potentially we can hopefully make that happen hopefully we're not too far lost.

Also it is interesting that developing countries with China and India perhaps in the lead where the future of the global environment will be decided are now on board with the case for sustainable development.

To live only for some future goal is shallow. It's the sides of the mountain that sustain life not the top.

Kids are meeting in coffee shops and basements figuring out what's unsustainable in their communities. That's the future.
