Environmental laws cover a myriad of topics including pollution, coastal-zone management, forest conservation, parks, wildlife, mineral development and cultural environment. This paper will deal with certain aspects of pollution in Singapore; the causes and sources of pollution, the types of control, particularly the relevant laws and the cost considerations of pollution control. No attempt will be made to define pollution, for the line is often difficult to draw and the delineation varies from person to person; instead the article will focus on forms of pollution such as water pollution, air pollution, noise pollution and pollution through solid wastes.
