Each year, over 13 million tourists visit the Indonesian island of Bali. But this tropical paradise faces a major trash problem, with non-biodegradable plastics a particular threat to the environment and wildlife. 4 years ago, local young people set up an NGO to tackle the situation: Bye Bye Plastic Bags. Founded by pre-teen sisters Melati and Isabel Wijsen, the group's activities include beach clean-up events and the provision of re-usable natural-fiber shopping bags to local stores. Local governments have also joined the fight, launching recycling schemes and school awareness campaigns. We follow 2 dynamic teenagers leading a team that is battling Bali's garbage problem.
