With help from the ocean's
natural wave action, the reduction in surface tension allows large surface slicks to separate into individual droplets that eventually sink to the sea floor.
Dr. Geh Min, former president of Singapore Nature Society, highlighted the unique role of tropical mangrove ecosystems in providing wildlife habitat, curbing coastal erosion caused by intense
wave actions or surface runoff, acting as a
natural purifier of water, while serving as sitea for human recreation.
