Their aim was to put a ban on the use and sale of single-use plastic bags in Bali to stop plastic pollution. Their first efforts focused on giving out non-plastic bags, such as net bags, newspaper bags, and 100% organic material bags, to local shops. They also began to teach locals and let them know about the pollution problems. 取り組み G-2 4 In order to educate all the island on the dangerous effects of single-use plastic bags, Melati and Isabel thought that government policies needed to change. They decided that they should collect one million signatures so that officials would not ignore them. To collect that many signatures, they came up with a great idea: collecting signatures at the very busy Bali International Airport. They went there and talked with officials, but these people wouldn't let them do so at first. The sisters talked again and again, and finally they were allowed to collect signatures there.
