Water is required to support biodiversity. Without sufficient water, stresses on species increase global biodiversity losses. ... Biodiversity supports water and nutrient cycling in soils and therefore plants, including all food crops. Together these processes control land erosion and regulate water quality.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.Wetlands provide many societal benefits: food and habitat for fish and wildlife, including threatened and endangered species; water quality improvement; flood storage; shoreline erosion control; economically beneficial natural products for human use; and opportunities for recreation, education, and research
