<p>Melati and Isabel Wijsen were only 10 and 12, respectively, when they started on a course of activism that has drastically decreased the global usage of single-use plastic. The young women were inspired by the country of Rwanda's ban of polyethylene bags in 2008, and decided to try to get their native Bali to do the same.
