Professor David Hume, Professor of Mammalian Functional Genomics, Director of The Roslin Institute and Research Director, Royal (Dick) School of Veterinary Studies, University of Edinburgh, presents "The Genes in our Food". There are very few "natural foods" and if we relied on them as a sole source of nutrition, the current world human population would collapse. Almost everything that we eat is GM as a result of human intervention. Modern technologies have revolutionised the ways in which we can modify our foods. Instead of selecting GM variants that arise by chance based upon their desirable traits, we can select them based upon their DNA sequence. We can produce transgenic plants and animals with new genes and we can edit the genome to produce variation that could have arisen naturally. Professor Hume discusses the ways in which these technologies can contribute to sustainable increases in productivity to feed a growing human population. Recorded on 12 November 2013.
