The past year's natural disasters have highlighted the invaluable contributions of volunteers in our communities. They have volunteered their time, energy and skills to save lives and to rebuild communities. In this they joined countless people around the world who volunteer every day in response to 'silent crises'. These often unsung heroes understand all too well that poverty, disease and famine are just as deadly and destructive as earthquakes, hurricanes and tsunamis.

Today, no walls can separate humanitarian or human rights crises in one part of the world from national security crises in another. What begins with the failure to uphold the dignity of one life all too often ends with a calamity for entire nations.

The report produced by my commission, the Global Commission on Elections, Democracy and Security, in 2012 showed the corrosive impact of money in US politics, for example, which undermines the legitimacy of the democratic system in citizens' eyes. Such perceptions partly explain the rise of a phenomenon like the success of Donald Trump.

As we move forward, you cannot resolve the potential food crisis or shortages without science being part of the solution. Science has to be part of the solution but African governments - and these are decisions for governments, whether they embrace or do not embrace genetically modified food - and for the moment, most African companies do not accept genetically modified seeds.

Let us remember the large numbers of citizens who, day in and day out, through acts of volunteerism large and small, bring hope to so many of the world's disadvantaged. Let us ensure that this wonderful resource, available in abundance to every nation, is recognized and supported as it works towards a more prosperous and peaceful world.

We're all human. After 10, 15 years you get tired, you run out of steam and ideas, you have to give a chance to somebody else. And whether you yourself are inclined to stay on, all those around you are pushing you to stay on for what they will gain.

How can you have a world of today where India is not represented in the Security Council; Japan, the second contributor, is not there; the whole continent of Africa, soon to be 54 countries, don't have a single permanent seat; and Latin America is absent? It's not realistic.
