You dive down into a undersea meadow. Surrounded by blades of seagrass up to a meter tall, you begin to notice the abundant life all around. Schools of baby fish hide within the grassy maze as emerald sea slugs graze algae off the blades. Seagrass is an ocean-dwelling flowering plant, which provides a home for countless creatures. But these habitats are threatened around the world.

Hakai Institute researchers are mapping the seagrass meadows and cataloging their biodiversity to establish a baseline understanding of seagrass habitats along the Central Coast of British Columbia and how these seagrass meadows are changing over time.

Hakai has been making some beautiful educational videos. Next, watch Beauty and the Feast: When Herring Come to Spawn, When Your Job Is Saving The Ocean from Mashable, and why is biodiversity so important? from TED Ed.
