摘要：Every wetland habitat along the entire continental shelf and beyond into tidal creeks and canals, acts as a natural filter for terrestrial pollutants and sediments (Figure 1). Whether one thinks that these ecosystems form in relationship to their biota or in relationship to their environment in autogenic or allogenic succession processes [1], all schools of thought tend to agree on the relevance of these ecosystems. By offering their filtration they offer a worldwide system of healthy kidneys for the body of the Earth. The water pulses into and out of these habitats as blood through veins, bringing in nutrients and removing potentially harmful elements. Delaware is facing the question of how to address concerns over sea levels rising and deciding what actions are necessary to prevent further degradation of the wetlands along its coasts. These examples serve to highlight a small portion of a much larger problem.
