Melati and Isabel are on a mission to stop plastic bags from suffocating their beautiful island home of Bali. Their efforts are paying off and have achieved major changes. Kids may only be 25 percent of the world's population, but they are 100 percent of the future. Sisters Melati and Isabel are on a mission to ban plastic bags in Bali. Inspired by similar measures in other parts of the world, Melati (15) and Isabel (13) launched the social initiative Bye Bye Plastic Bags in 2013, which has become a well known international movement of inspiration, youth empowerment, and of course, saying no to plastic bags. The two sisters, who frequent the environmentally minded Green School along with a crew of like-minded motivated kids, continue to ask the question: How can they make a difference in the world? This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx
