I found this article on a website called scientific american.

The topic of this article is why wetlands are so important to preserve.

Wetlands include swamps, marshes, bogs, riverbanks, mangroves, floodplains, rice fields—and anywhere else. According to the U.S. Environmental Protection Agency (EPA), that saturation with water is the dominant factor for determining the nature of soil development and the types of plant and animal communities there. They are widespread in every country and on every continent except Antarctica. If all the world’s wetlands were put together, they would take up an area one-third larger than the United States. According to Wetlands International, a global non-profit dedicated to the conservation and restoration of wetlands around the world, wetlands are on the “front-line” as development pressures increase everywhere.

In my opinion, environmentalists, biologists and others concerned about the health of the planet and its inhabitants recognize the key role wetlands play in life on Earth, and if they really recognize the danger the animals are in, then they should do more to help. While the issue lingers on in municipal planning meetings around the country, the federal government does what it can to protect wetlands. It does so through regulations spelled out in the Clean Water Act, which include providing tax incentives for selling or giving wetlands to land trusts or other conservation groups, via cooperative efforts with state and local entities, and by acquiring wetlands outright to add acreage to public lands systems. And several states have passed laws to regulate activities in wetlands, and many municipalities include wetlands conservation in their development permitting and zoning processes.
