Sark"s reputation may well be built on tradition and fleeting nostalgia, but subtle advances are creeping into everyday life. The island"s doctor and first responders now use electric bicycles. There is an ambulance, but the driver cabin has been purposefully removed and the body is now pulled by a tractor. Behind the island"s Stocks Hotel, a permaculture garden produces organic vegetables that are fertilised using horse manure from the carriage company. Such a space has become a study in revitalising the island"s natural ecosystems.
