Did You Know? The idea of a wetland may strike you as strange, because we usually think of the world as either wet (rivers, lakes, oceans) or dry (mountains, plains, coasts). But wetlands are both. They're soggy enough that you wouldn't want to go camping in them, but there's enough soil for plants like reeds, bushes, and even trees to take root and grow. In the past, many wetlands were filled in to make farmland or to develop the area for housing—more than half of the original wetlands in the continental United States are gone. Today, however, scientists have discovered that wetlands can act like huge filters, removing pollutants from the waters of an area before those substances can do harm. They can serve as reservoirs, and they may help in flood control by absorbing excess water. Wetlands are also home to many different plant and animal species that have evolved to live in the wetland's unique conditions.
