In BALI much of the trash used to be biodegradable, such as banana leaves that rapped food items. Nowadays our modern words raps everything in plastic, which largely can’t be recycled.
INSTEAD the many rivers or the little streams have become the convenient conveyor belt of trash, that runs right out into the evil ocean.
Many old Balinese collect the recyclable bottles and already do sell them back to be recycled. That part is already in place and offers a meager but noticeable sustenance.
