A lone farmer drives his Ford tractor across the expanse of a green English field. Using wide arms mounted on the rear,  chemicals reach out to cover a wide surface area, spraying what are possibly pesticides onto growing crops, the mechanised machine passes over the grasses of cereals that are thriving and maturing on this summer's day. The land rises up behind the farmer, a steeper escarpment of the landscape in the county of Kent - a fertile region of souther-eastern Britain, otherwise known as the Garden of England.
