When globalisation means that many of the services that individual governments used to have direct power over are privatised, in education and health, even prison services, nonetheless national sovereignty still needs to be exercised.

I was influenced at an early age by Gandhi, and I have read many biographies of him. I have been greatly influenced in the last twenty years by Mandela. It is amazing that he has managed to keep such a balance, that he came out of prison after such a long time as a rounded, holistic person who could reach difficult accommodations with generosity.

Climate change is the greatest threat to human rights in the 21st century.

We need to understand that we need to get the work-life balance better for both men and women - by men taking on more of those roles of homemaking and child rearing - it's an important area that we still haven't got right. I do worry; it's not just in the United States, it's also in parts of Latin America.

I'm struck by how very few people outside a rarefied world of true believers understand what you mean when you say human rights - that includes development experts and economists who are very keen to implement the UN Millennium Development Goals. They've told me quite frankly, that they don't know exactly what a human rights approach is.

It is a great problem for the true international agenda of human rights that the United States, uniquely among industrialised countries, has not ratified three main instruments, has not ratified the Covenant on Economic, Social and Cultural Rights, or the Convention on the Rights of the Child, or the Convention for the Elimination of Discrimination Against Women, and we could have so much richer a debate and dialogue on international human rights standards if the superpower would sign up to the agenda.

There's a worldwide linking of environmental activists, developmental experts and human rights advocates. And they're using the two frameworks, in particular environmental standards and human rights.
