Carbon sinks are essential for global warming and ecological balance. With "Taiwan's Natural Carbon Sequestration" as the core, learning materials for 9-12 year old students are created to gain an in-depth understanding of the carbon sequestration ecology through visual charts and digital experiences. The green, yellow, and blue carbon sinks are used to guide the situational experience, motivate parents and children to invest in environmental protection and sustainable development, and promote the mission of carbon reduction and environmental protection.
