Wetlands are places where land and water meet. They can be marshes, wet grasslands, or coastal areas. They may look quiet, but they do important work.
First, wetlands hold water slowly. During heavy rain, a wetland can act like a sponge. It stores water and reduces the amount that rushes into rivers and towns.
Second, wetlands are homes for many living things. Birds, fish, insects, and plants find food and safe places there.
Wetlands also help clean water. Plants and soil can catch dirt and extra nutrients before the water moves on. Protecting wetlands protects nature, but it also protects human life.
