I thank my friend the hon. Member for that intervention. I will be coming to that point shortly.
It is agriculture that gives those of us who are worried about the environmental effects the time and space to do that worrying. Agriculture is what lies behind civilisation, because food production and food security—the nourishment of people who can be productive in other ways because they do not have to find or produce their own food—is what underpins the modern economy. Take away the food supply and we destroy the rest of the economy.
