Wetlands serve a host of important ecosystem functions and are valuable also to human society. Among the important ecosystem functions are that they are high productivity environments and are also often diverse. The high productivity also has important consequences to humans in that they tend to support a large number of consumers many of which have commercial value.

In addition to the commercial and recreational values, other important human society values are:
* Flood and storm buffers
* Pollution filters
* Sediment filters (regarding navigable waterways)

A recent assessment of the monetary value of our natural wetland ecosystems estimated them at US$ 14.9 trillion, fully half of the value of the estimated value of all terrestrial ecosystems, despite the fact that they only account for a small fraction of that total area (see reference below).

Wetlands are aquifers for the environment. In other words, wetlands and marshes are like natural filters which filter dirt and other toxins from the water.
