One of the most important functions of wetlands is the ability to purify water and preserve water quality. Despite the integral role of wetlands in maintaining healthy ecosystems, they continue to be at risk of impacts by development, lack of legal protections, pollution, and the negative influences of climate change. Wetlands provide numerous ecosystem services; one of which being their ability to improve water quality and help in maintaining water quantity. These critical services are only expected to become more important as freshwater becomes an increasingly limited resource. It is therefore imperative that efforts are taken to preserve and restore our nation’s wetlands in order to retain our natural healthy waterways.
