The Great Famine is a period of our history that we need to know in great detail in order to understand its continuing impact on us as a people. Its causes were complex. We can't apportion blame simplistically but rather [must] understand that blame has to be shared in different areas and levels of society. It was the very poorest of the poor, the small tenants and cottiers, who really suffered. Others were less affected. But most of all I welcomed the commemoration because it was a moment to look into our past and realize the courage and resilience of those who survived.

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.

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.

Tackling the issue of climate change presents us with an inflection point in human history - a climate justice revolution that separates development from fossil fuels, supports people in the most vulnerable situations to adapt, allows all people to take part, and, most importantly, realise their full potential.

The first thing to recognize is how fortunate Ireland is to be an island off the west coast of Europe, and therefore helped by the prevailing winds to escape the effects of acid rain and other problems. We were also lucky not to have had the same kind of industrial revolution and industry as some other countries. Our problem now is to create employment, but to do it in ways that value our environment.

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.

It is people who go through suffering that have an empathy for the suffering of others.
