The whole imposing edifice of modern medicine is like the celebrated tower of Pisa - slightly off balance.

The world's forests need to be seen for what they are - giant global utilities, providing essential public services to humanity on a vast scale. They store carbon, which is lost to the atmosphere when they burn, increasing global warming. The life they support cleans the atmosphere of pollutants and feeds it with moisture. They act as a natural thermostat, helping to regulate our climate and sustain the lives of 1.4 billion of the poorest people on this Earth.

Climate change should be seen as the greatest challenge to face man and treated as a much bigger priority in the United Kingdom.

We have spent the best part of the past century enthusiastically testing the world to utter destruction; not looking closely enough at the long-term impact our actions will have.

Personally, I have been very impressed by the slow food movement. It is about celebrating the culture of food, of sharing the extraordinary knowledge, developed over millennia, of the traditions involved with quality food production, of the sheer joy and pleasure of consuming food together. Especially within the context of family life, this has to be one of the highest forms of cultural activity.

Your greatest achievement is to love me.
