We meet the sibling trio behind Sungai Watch, a nonprofit on the tropical island of Bali that is removing plastic from Indonesia's rivers.
Indonesia ranks as one of the world's biggest contributors to ocean plastics, and a lot of it comes from rivers.
The local nonprofit Sungai Watch saves about 3 metric tons of trash from entering the ocean every day with simple barriers and manual labor.
We visited the island of Bali to meet the three young siblings behind the nonprofit and learn why a tropical paradise has a huge trash problem.
