The introduction begins witha brief overview of wetlands: their nature and services offered. These wetlands are ecosystems with water that is static or flowing and characerized by emergent , floating and submerged aquatic vegetation. Some of the services provided by wetlands are fish and fiber, water supply, water purification, flood regulation, recreational opportunities and tourism. It then details the importance of wetlands for water purification.Toxins enter the wetlands through farms, factories and runoff. These toxins are broken down or otherwise buried using a variety of bacteria.
