Florida Everglades
Hope this helps! wetlands..... purify water, protect from flooding, provide habitats for animals, and soak up flood water.
The Florida Everglades, located in southern Florida, is one of the largest wetlands in the world.
This is because wetlands have organisms in them that act as filters and clean the water. So it conserves water by cleansing it for us and then making it able for us to drink. I think that would be considered conserving.
Over half of the nation's wetlands have been destroyed since the western advancement of the 1600's. ~100,000,000 acres have been lost. See (http://geochange.er.usgs.gov/sw/impacts/hydrology/wetlands/).
