Question: I have many concerns about GM but the greatest are: 1. The potential effects on ecosystems by way of altering the genetic makeup (carefully engineered by nature) of other species; I think you have to some extent addressed this already; and 2. The prospect of more, and more extensive, monoculture and the resulting damage to ecosystems/biodiversity. We have already lost much of our biodiversity due to the move away from mixed farming and towards monoculure. As I see it, any increase in the use of GM will exacerbate this. Would the epxerts care to comment. Thank you.
