Our guest is Yodogawa Technique, an artist who transforms trash and flotsam into stunning collages. He travels worldwide, interacting with local communities to create thought-provoking works. In the Maldives he formed a huge fish with the plastic bottles that are endangering its coral reefs. In memory of all that was swept away by the devastating tsunami of 2011, he created a "Wakabayashi 100 Years Swing" using what was left of the windbreak forests. His work has been featured in school textbooks to inspire eco-awareness.
