MELATI & ISABEL WIJSEN

Founding the Indonesian nongovernmental organisation (NGO) Bye Bye Plastic Bags (BBPB) when they were just 10 and 12 years old, these sisters aimed high – trying to get people in Bali to say no to plastic bags. Their efforts have paid off, with Bali banning single-use plastics in 2018.

The sisters are continuing on their journey with their NGO, which has grown into an international movement for youth empowerment, while still focusing on plastics.
