Coastal wetlands embody saltwater marshes, estuaries, mangroves, lagoons, and even coral reefs. Human-made wetlands embody fish ponds, rice paddies, and salt pans — though naturally occurring salt pans additionally exist. Each of those has an environmental function to play.

Environmental Value of Wetlands

Inland wetlands perform like sponges, absorbing and storing water to scale back flooding throughout heavy rainfall. Also like sponges, wetlands launch saved water throughout dry seasons, delaying droughts and minimizing water shortages.

Coastal wetlands scale back storm surges and floods, defending coastlines from harm. A 2017 study discovered that coastal wetlands prevented $625 million in direct flood damages throughout Hurricane Sandy, lowering damages as much as 30% in some areas.

But one ecological service offered by wetlands has a worldwide impact. Wetlands are a carbon sink. Because they take up and retailer carbon, wetlands are crucial for slowing local weather change. Peatlands cowl solely 3% of the Earth’s floor, but retailer at the very least twice as a lot carbon because the world’s standing forests. In truth, salt marshes, mangrove forests, and seagrass meadows are every more efficient carbon sinks than rainforests.
