When my parents were growing up the world's population was under three billion. During my children's lifetime, it is likely to exceed nine billion. You don't need to be an expert to realise that sustainable development is going to become the greatest challenge we face this century

However much I dislike the idea of abortion, you should not criminalize a woman who, in very difficult circumstances, makes that choice.

We have a situation where we are rich really as a world overall, and yet we have the capacity to destroy ourselves, either through nuclear weapons or through environmental degradation, and we allow the life chances of hundreds of millions of people to be destroyed because we haven't found the will to tackle it

If we don't act now, then we will go back to what has happened before and then of course the whole thing begins again and he carries on developing these weapons and these are dangerous weapons, particularly if they fall into the hands of terrorists who we know want to use these weapons if they can get them.

I do not want to end up with an American style of politics, with us going out there beating our chest about our faith. Politics and religion - it is not that they do not have a lot in common, but if [religion] ends up being used in the political process, I think that is a bit unhealthy.
