Britain's leading organic body, the Soil Association, is to ban all but "ethical" air-freighted food in a move designed to throw a financial lifeline to poor countries while cutting pollution linked to climate change. By 2011, farmers and distributors must be Fairtrade or meet the Soil Association's own ethical standards if they are to be certified for sale here, said the organisation. At present, only a "small minority" of growers in developing countries meet the new rules, but the Soil Association said it hoped they would be able to respond in time for the ban – a compromise between development and the environment.
