In this episode, Rachel takes us with her to Bali in Indonesia. Accompanied by a guide, she crosses a village whose origins remain a mystery to everyone. The protection of the environment is a priority for this town and its inhabitants. Then we follow Jen and her family on the East coast of Tasmania where they have decided to spend their holidays. Like many tourists, they will go to the "Becheno Blower Well". Then, they will take you to discover the seabed through a trip on a glass-bottomed boat. This is a place that, just like Bali, is doing its best to preserve the environment and biodiversity.
