Question
While future sea level rise driven by global climate change is predicted to have significant, and expensive, impacts on coastal development and populations, there is a growing sense of urgency about its effects on coastal wetlands and the essential ecosystem services they provide. Ongoing studies by scientists from the U.S. Geological Survey explore the vulnerability of coastal wetlands in regions of varying tidal ranges and sediment supply to different rates of possible sea level rise. They conclude that many are unlikely to keep up with future sea-level rise and will become submerged and disappear. Read the linked article and think about the importance of these often under-appreciated coastal environments. Then answer the following questions.Explanation / Answer
Wetlands are important because they are protecting the ocean and environment of the earth. And they can major control coastal erosion and flood protection.
Ecosystem services means benefits of people obtain from ecosystems. These including provisong services such as food and water; regulating, such as the control of climate and disease; supporting services such as soil formation and nutrient cycling and cultural service such as spiritual, religious and recreational benefits.
The essential services do coastal wetlands provide are following.
Coastal wetlands can prevent coastline from erosion.
It can protect upland area from flooding.
It can filter the pollutant water then it is discharged in the ocean.
It can provide also provide Carbon sequestration, commercial fisheries and recreation etc.
