In the first of Talking of Food's series of interviews and debates on genetically modified (GM) foods, agricultural journalist and author, Diane Montague, interviews Vivian Moses, Visiting Professor of Biotechnology at King's College London, and the resulting discussion sets out what GM is and what the major issues are. It is a fitting introduction to the further discussions.

We who live in Britain and buy our food here (only 60% of which is grown in the country, with the rest imported) cannot help but be interested in the current state of UK food production and its future prospects. Phil Bicknell, Head of Food & Farming at the National Farmers Union, fields questions from biotechnologist Vivian Moses representing the inquiring British layman. 

We are all aware of the threat to existence of climate change. But how is climate change measured; how do we know that sea levels are rising, when we look out to sea and see the waves rolling in, every time different because of wind and weather, and we see the tide ebbing and flowing because of the effect of the moon. To help us understand this, Vivian Moses talked to Ross Reynolds, Associate Professor in the Department of Meteorology, Reading University.
