How wetlands function with other Earth systems such as the atmosphere, hydrology, and as habitat for wildlife and humans
Consider the value of wetlands to societies

Benefits to society for different wetlands are listed here. Click on more at the end of each section to learn how these benefits come about. There is a special note here about underwater grasses.
Salt Water Marshes: hold and regulate temperature of soil, trap sediments, slow flooding and erosion, feed detritus to ocean, carbon sequestering, oxygen during photosynthesis, salt tolerant, hay, seeds for wildlife and art, grasses for art and textiles, scenic and tourism value, wave breaker, bird nesting sites, DNA, noise abatement More
Mangrove swamps: hold and regulate temperature of soil, trap sediments, slow flooding, and erosion, salt tolerant, seeds for wildlife and art, detritus to ocean, carbon sequestering, oxygen during photosynthesis, wildlife nesting habitat, fin fish and shell fish nursery among roots, fishing platform for humans, wood for humans, scenic and tourism value, wave breaker, DNA, noise abatement, pharmaceuticals More
Fresh water tidal or riparian wetlands: hold soil, trap chemicals and sediment, produce detritus, seeds, wood and grasses used by humans and wildlife, flowers, bird habitat, fur bearing mammals, reptile skins, oxygen in photosynthesis, nitrogen fixing, sulfur cycle, flood control, fish, water temperature regulation, noise abatement, scenic value, recreation, DNA, enzymes for industry and pharmaceuticals, food crops, fish, amphibians, tourism More
Inland (lake edge, fens, bogs, meadow, prairie, playa) freshwater wetlands: trap chemicals and sediment, nitrogen and sulfur cycles, carbon dioxide sequestering, wildlife, water temperature and chemistry regulation, drought and flood protection, wood, grasses, fur bearing mammals, amphibians and reptiles, scenic value, noise abatement More
In the past wetlands were drained for development. Today they are threatened by pollution and climate change that is changing their hydrology, either flooding them or drying them up. National parks are one place where wetlands are protected from development.
