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

A lot of young people are very cynical about the political framework because they see the countries that preach democracy and human rights being countries largely responsible for the problems in their region.

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.

I felt when I was elected that the most important task on this island [Ireland] was to extend the hand of friendship right across the board to the people of Northern Ireland, to have the beginnings of a real peace process. In consequence, although I have no role in intergovernmental talks or political discussions, that would be my very top priority.

In human rights theory it is very important that governments still have the primary responsibility for the standards and provision of such services even if they no longer deliver them. They must insist that the private sector delivers without discrimination. So governments still have responsibility, including the need to influence business.

One of the richest countries in the world - the United States of America - is facing a real ethical dilemma in terms of providing equitable access to health care.

Since 9/11 the United States has been followed by countries with bad records, such as the former Soviet Union countries, into erosions of human rights. Because the United States has changed its standards it is undermining civil liberties elsewhere.
