Where the wax covered the cloth, it remains undyed and retains its natural color while the rest of the cloth absorbs the dye. The chemicals are inhaled by the dye worker. In addition, any unused dye is simply dumped into the nearest stream. The next day, it would be bright orange. It's extremely polluting and kills all life in and around the streams.
Tourism also adds to congestion and trash problems in Indonesia.
Bali has limited means of disposing of solid or liquid waste so trash is commonly burned, releasing toxins into the air. In addition, Denpasar's overflowing landfill leaches into Benoa Bay. Auffrey says it's impossible to tell as Bali only tests its air quailty once a year. Local officials don't have sufficient funds to test more often. Not Bali for Tourism.
