Carbs vs cars

Sir: I enjoy Rod Liddle but my 13-year-old grandson points out a flaw in his recent piece (‘Green taxes are witless nods to fashions’, 9 August). He notes that, pace Liddle, it is not protein but carbohydrates that give you the energy to walk to the shops. So the killing of cows and the associated packaging for supermarkets doesn’t come into it. Driving a car is indeed less environmentally sound than walking.
