Organic/natural farming is not just about indirect environmental benefits:
The carbon-footprinting process often produces surprises. An environmentally conscious consumer in the crisps aisle of the supermarket will probably be thinking about packaging or “food miles”. The Carbon Trust reckons that about 1 per cent of the climate impact of a packet of crisps is from moving potatoes around. The largest single culprit is the production of the nitrogen fertiliser, and half of the climate impact in general takes place at the agricultural stage.
