The town of manville, New Jersey, is where the Johns-Manville Company manufactures the largest amount of asbestos products. Its profits have been ploughed back for the people's welfare. The incidence of lung cancer among the company's employees is four times the national norm. Mesothelioma--a form of chest or abdominal cancer--that accounts for only one out of every 10,000 deaths in the general population, had in eight years claimed the lives of some 58 Manville residents.
