"Who said you can't change anything? You've changed me." The beautiful Little Liuqiu Island is the natural habitat for the endangered green sea turtle. Xiao-Lu is passionate about green sea turtles and is wholeheartedly dedicated to conservation research. As an anti-plastic activist, Xiao-Lu encountered a series of dilemmas which led to many disagreements and the eventual breakup with her boyfriend. As green sea turtles hatch and head into the ocean, only one in a thousand hatchlings will survive and safely grow into adulthood. It takes as many as 50 years for green sea turtles reach sexuality maturity and at that point, they return to their nestling beach to lay eggs. But what will become of their habitat after 50 years? Tourism has stimulated the economy of beautiful Little Liuqiu Island but how will it find a balance between tourism and marine conservation?
