A giant belt of seaweed, over 5,000 miles long, is floating across the Atlantic Ocean. Pollution from farms and cities feeds this seaweed, causing it to grow too fast. When it washes onto beaches, it rots, creates bad smells, hurts sea life, and ruins tourism. To fix this, experts suggest we must better track these blooms and reduce water pollution from land to keep our coastlines clean and healthy for everyone.
