A man points towards a man smoking a cigarette along a street in central Beijing March 23, 2012. Smoking could kill about 1 billion people this century, authors of the fourth edition of the Tobacco Atlas said at the book's launch in Singapore on Wednesday. The book is published by the American Cancer Society and World Lung Foundation. Michael Bloomberg's charitable foundation will commit $220 million over the next four years to fight tobacco use globally, including for the funding of legal challenges against the industry. But Bloomberg's initiative is likely to face opposition in China, the world's largest producer and consumer of tobacco with more than 300 million smokers, from a powerful state monopoly and local officials who fear a fall in tobacco profits. The tobacco industry provides nearly one-tenth of tax revenues in China. REUTERS/David Gray (CHINA - Tags: HEALTH)
