Yesterday was World Wetlands Day, and salt marshes are some of the most important wetlands in the world. Found along the entire U.S. coastline (and every continent except Antarctica), salt marshes absorb carbon, protect coastlines from erosion, filter pollutants, provide many economic benefits, and provide habitats for many important fish and shellfish species we eat. They also act as natural buffers when floods and hurricanes hit, making them a really important climate solution. But they’re under threat due to historic human ditching, invasive green crabs, and worsening sea level rise. Today, we explore why salt marshes are important, what challenges they face, and how we can help them moving forward. With special guest Dr. Sergio Fagherazzi: Professor of Earth & Environment at Boston University.
