Beneath the waves along many coasts grow wide meadows of seagrass. These underwater plants are surprisingly important. They store large amounts of carbon, provide shelter for young fish, and keep the water clear. Sadly, much of the world's seagrass has disappeared because of pollution and coastal building. Scientists warn that ( 1 ). In England, a group of volunteers decided to act. They collected thousands of seagrass seeds by hand and planted them in a damaged bay. The work was slow and difficult, ( 2 ) the seeds were tiny and the sea was often rough. Even so, the volunteers returned season after season. Their patience paid off. New seagrass began to spread across the seabed, and fish and seabirds returned to the area. ( 3 ), the project showed that ordinary people, not just experts, can help restore nature.
