What are 3 reasons wetlands are important?
Wetlands provide habitat for thousands of species of aquatic and terrestrial plants and animals. Wetlands are valuable for flood protection, water quality improvement, shoreline erosion control, natural products, recreation, and aesthetics.
Why wetland is important for human?
Wetlands are an important part of the ecosystem that regulate water and have a unique role in maintaining the food chain. … Hence wetlands functions as a corridor connecting marine, aquatic and terrestrial ecosystems. As a part of the freshwater ecosystem, wetlands play a crucial role for humans as well as biodiversity.
How does wetlands improve water quality?
Wetlands can improve water quality by removing pollutants from surface waters. … As water from a stream channel or surface runoff enters a wetland, the water spreads out and flows through dense vegetation. The velocity of the flow is reduced, allowing suspended material in the water to settle to the wetland surface.
What effects do humans have on wetlands?
Human activities cause wetland degradation and loss by changing water quality, quantity, and flow rates; increasing pollutant inputs; and changing species composition as a result of disturbance and the introduction of nonnative species. You may also read,
