The conflict in the Middle East needs to be solved for the same reasons. It is necessary to reach a two-states solution built on international law for sustainable peace and development and it can only be achieved through joint efforts by the international community.

I think what the Nobel committee is doing is going beyond war and looking at what humanity can do to prevent war. Sustainable management of our natural resources will promote peace.

When resources are degraded we start competing for them whether it is at the local level in Kenya where we had tribal clashes over land and water or at the global level where we are fighting over water oil and minerals. So one way to promote peace is to promote sustainable management and equitable distribution of resources.

When I think about the world I would like to leave to my daughter and the grandchildren I hope to have it is a world that moves away from unequal unstable unsustainable interdependence to integrated communities - locally nationally and globally - that share the characteristics of all successful communities.

If you believe that health care is a public good to be guaranteed by the state then a single-payer system is the next best alternative. Unfortunately it is fiscally unsustainable without rationing.

That the AIDS pandemic is threatening sustainable development in Africa only reinforces the reality that health is at the center of sustainable development.

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.

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.

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

Innovations that are guided by smallholder farmers adapted to local circumstances and sustainable for the economy and environment will be necessary to ensure food security in the future.

Any serious shift towards more sustainable societies has to include gender equality.

Gender equality is more than a goal in itself. It is a precondition for meeting the challenge of reducing poverty promoting sustainable development and building good governance.

Global markets must be balanced by global values such as respect for human rights and international law democracy security and sustainable economic and environmental development.

I firmly believe that we can have a healthy environment and a sustainable timber industry.

You can't have a sustainable US economy without a great education system. Teach students to do the job right. You don't have an innovative economy unless you have a great education.

For wide swaths of training and education there are valuable spillovers which mean that the private sector needs support from the government. That is why I have been so determined to protect and grow apprenticeships and put higher education on a sustainable footing.

Education is a human right with immense power to transform. On its foundation rest the cornerstones of freedom democracy and sustainable human development.

I still indulge in a glass of wine or chocolate - treats are mandatory. Without deviating from the day-to-day healthy diet once in a while it wouldn't be sustainable for me and that's what I wanted: an approach to eating to last my entire life.

A safe and nutritionally adequate diet is a basic individual right and an essential condition for sustainable development especially in developing countries.

We have got to change our ethics and our financial system and our whole way of understanding the world. It has to be a world in which people live rather than die a sustainable world. It could be great.
