Understanding Wetlands

The video introduces the concept of wetlands, highlighting their importance as ecosystems that provide wildlife habitat and support coastal economies. It explains different types of wetlands, focusing on Georgia's coastal salt marshes and their role in preventing flooding and pollution. The video also covers the significance of estuaries in supporting marine life and the threats wetlands face due to land use changes. Finally, it emphasizes the need to protect remaining wetlands and teaches viewers how to observe and evaluate wetland health.
