G.B. ENGLAND. London. The regeneration of the London Docklands. On the 'Urban Farm' on the Isle of Dogs there are 52 sheep, bred as part of a community initiative designed to help the city children at the local schools have an understanding of nature and farming. An experience outside their everday lives. These sheep graze on a quarter of a million pounds worth of real estate. Everywhere else in the eight square miles running eastwards from Tower Bridge building land is now worth four million pounds an acre. 1987.
