The United Nations General Assembly adopted Resolution A/76/L.56 on May 23, 2022, sponsored by Sri Lanka and co-sponsored by 24 countries, proclaiming March 1 as World Seagrass Day. The World Seagrass Association provided close support. The first observance was on March 1, 2023.
Get ready to dive into the wonderful world of seagrass on March 1 for World Seagrass Day! This special day was first celebrated in 2019 by the Seagrass Growers Association as a way to raise awareness and appreciation for these important marine plants. Seagrasses play a crucial role in maintaining healthy coastal ecosystems, providing food and shelter for a variety of marine life. They also help mitigate the effects of climate change by storing carbon and protecting shorelines from erosion.

WHY THIS DAY MATTERS
Unfortunately, seagrass meadows are facing numerous threats such as dredging, pollution from agriculture and urbanization, and overfishing. By raising awareness on World Seagrass Day, we can promote the importance of protecting and preserving these habitats for the sake of our oceans and the creatures that rely on them.
Seagrass plays a crucial role in maintaining healthy coastal ecosystems. It provides shelter and food for various marine animals, helps to reduce erosion and absorb excess nutrients in the water, and also acts as a carbon sink, helping to mitigate the impacts of climate change.
Healthy seagrass beds support diverse species of fish, invertebrates, and other marine life. These plants provide important nursery areas for juvenile animals, which contribute to healthy populations in surrounding areas, making it an essential component of the ocean's biodiversity.
