Xiaoliuqiu is a small island in the south of Taiwan surrounded by a beautiful sea with coral reefs, also known as "Sea Turtle Island." However, the rising number of tourists has created massive amounts of plastic waste, posing a major threat to the local environment. In order to restore the natural beauty of the island, divers, innkeepers, shopkeepers and other residents are working together to turn the tide. We follow the efforts of a small island that has initiated a number of novel projects in pursuit of zero plastic waste.
