Is the Seagrass Always Greener? A Climate Guide to Seagrass

Seagrass absorbs carbon up to 35 times faster than a rainforest, making it a climate superhero. So why are its populations declining so fast?


Though we might not think about it much, seagrass is really important. It provides food and shelter for many fish and crustaceans, a source of oxygen for the ocean, and a special ability to absorb carbon that makes it an even more efficient carbon sink than forests. But due to temperature changes, extreme weather, agricultural runoff, and other human activities, seagrass populations are declining fast, which could exacerbate climate change, cost the economy, and destroy marine ecosystems. Today, we discuss what issues seagrass faces, why seagrass is so important, and what we can do to protect it. With special guest Dr. Lina Mtwana Nordlund: Assistant Professor of Earth Sciences, Natural Resources and Sustainable Development at Uppsala University.
