Wetlands provide important habitat and protect against floods. They establish habitats, form protective barriers, trap floodwaters, and recharge groundwater. The North American Wetland Conservation Act of 1989 aimed to protect wetlands and waterfowl. It created thousands of projects and jobs, and raised $3.5 billion. Experts say wetlands are highly productive and help reduce storm surges. However, development and pollution threaten wetlands, so laws and education are needed to protect these vital ecosystems.
