Pressures on coastal and marine systems are growing more intense. As rapid
development and population growth continue in coastal areas, increasingly heavy
demands will be placed on the natural resources and remaining natural habitats
along the coasts.
On islands and in coastal areas, the main types of pollution in coastal waters
include sediment runoff, sewage, solid waste, high nutrient loads, synthetic
organic chemicals, oil, and pathogens. These result in eutrophication, and deteriorating
of water quality, which have adverse effects on coastal ecosystems and their
living resources.
