After the 1970s, there was a significant decline in wetland resources and ecosystem services in the US. This decline can be attributed to various factors, including urbanization and land development, agricultural practices, pollution, drainage for infrastructure development, and the introduction of non-native species.
Urbanization and land development led to the destruction and fragmentation of wetlands as they were drained or filled to make way for housing, roads, and industrial areas. This loss of wetland habitats resulted in a decline in biodiversity and the disruption of ecological processes.
Agricultural practices, particularly the increased use of fertilizers and pesticides, led to water pollution and eutrophication in wetland areas. This pollution not only harmed the wetland plants and animals but also affected the quality of water supplied to humans.
Wetland drainage for infrastructure development, such as the construction of dams and levees, further destroyed wetland ecosystems. Drainage reduced the water retention capacity of wetlands, leading to decreased water availability during dry periods and increased flooding during heavy rainfall events.
Additionally, the introduction of non-native species, such as invasive plants and animals, disrupted the natural balance of wetland ecosystems. These invasive species outcompeted native species for resources, leading to a decline in native biodiversity and altered ecosystem dynamics.
Overall, the combined impact of urbanization, agricultural practices, pollution, drainage, and the introduction of non-native species resulted in a significant loss of wetland resources and a decline in the provision of ecosystem services in the US after the 1970s.
