Over a decade, Earth Systems has already exceeded its safe boundaries, and distributive justice for them also exceeded their just boundaries in many aspects. Our world is constantly changing, including climate change. Planetary health is the pursuit of a desirable society that is sustainable and harmonious between humans and the planet, tackling various global issues and achieving the best health, well-being, and fairness. At the Planetary Health Alliance Japan Hub, we are currently engaging in discussions about setting a framework for planetary health which harmonizes with our cultural history or view of nature in Japan and other Asian regions. We welcome participation from people of all ages from various specialized fields, from students to seniors.
