Adopt-a-Species: Scan the QR code to see a list of currently endangered animals that Cortada has featured in his installations. Select one of the animals, take a stone, and mark it (using the acrylic paint pen) with the longitudinal degree (e.g., 90E) where your animal struggles for survival. Pledge an “eco-action” as a commitment to your chosen animal and place the stone in a visible location at home to serve as a daily reminder of your pledge. If you would like your marked stone to possibly be included in future Endangered World exhibitions, take a picture of it and share it, along with a brief description of your eco-action, on social media with @xcortada and #EndangeredWorld tags.
