ingapore's clean and green image is the result of more than two decades of public education campaigns and strict laws against littering. Littering of any kind is subject to up to a S$1,000 fine for first offenders, and, for repeat offenders, up to S$2,000 coupled with a stint of corrective work order cleaning a public place. As an extension of the law against littering, the import, sale and possession of chewing gum is prohibited. Spitting is also punishable by law in Singapore. So beware the next time you wish to clear your throat.
