Scientists Revive Arctic Kelp With Simple, Cheap Method

Researchers in northern Norway have found a simple way to restore damaged underwater forests. This success could help fix marine ecosystems hurt by decades of overfishing. The solution focuses on bringing back humble algae, known as kelp. Kelp forests are vital. They provide food and shelter for many fish and other sea creatures. Past restoration attempts were complex and costly. The new method is different. It involves manually attaching young kelp to lines in the sea. This helps the algae regrow in areas where it had disappeared. The project shows that damaged Arctic waters can recover. Scientists say the technique is a low-cost, effective tool for large-scale marine restoration.
