The annual celebration of World Seagrass Day on March 1 aims to increase awareness of seagrass and its vital role in the marine ecosystem.

• The United Nations General Assembly declared it on May 22, 2022, after Sri Lanka passed a resolution emphasising the conservation of seagrass in marine environments.
• Seagrass is a flowering marine plant widespread along the world’s coastlines, serving as an essential food source for marine life and helping to maintain water quality.
• The seagrasses have been declining since the 1930s. International Union for Conservation of Nature (IUCN) categorizes nearly 21% of the world’s seagrasses as near threatened or vulnerable or endangered. Pollution, coastal development activities, and land-based run-offs are degrading the seagrasses.
