That was then, Gaunt, Couldn't be done now.
My home county of Essex is like a dustbowl in places from British farmers ripping out hedges 50 years ago in the interests (supported by the government of the day) of maximising food production post WWII.
We know much more know about the adverse effects of industrial farming, soil impaction by heavy machinery, topsoil blowing away from massive fields, fertiliser runoff into watercourses, and the importance of biodiversity. The EU farm payment scheme is quite hot on environmentally friendly farming practice. Let's hope we don't lose that emphasis in the future.
If it's any consolation, we have 19 acres of grazing, hay field, hedges and woodland. Not to mention a garden full of slugs... We have hedgehogs by the dozen.
