When a genocidal killing occurs, as happened in Rwanda, it is not just an internal domestic matter.

I can see the immense capacity of business to give leadership.

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.

Post-genocide Rwanda has managed to implement a good universal health insurance scheme that covers a large proportion of the population. This came about because of the severity of the country's problems and the resulting high proportion of women in the parliament and among professional caregivers, which had a positive effect on policy.

The UN may not be very effective but I am a fan of the idea of the United Nations. I have been there, I know the problems. To parody Winston Churchill: It is the worst system, except we don't have any other.

The fossil-fuel-based development model has not benefitted all people and those who have benefitted least are now suffering great harm in the face of climate change.

We need more emphasis on linking jobs and economic progress with environmental issues, and not allowing environmentally damaging industries to be brought into the country simply to provide employment. It's not easy to balance.
