The 12 Systems refers to the "human system", a concept developed by ecologist and eco-philosopher Feigenbaum, which refers to the 12 key elements of human civilization and society. These are life systems, physical conditions, politics of empowerment, economic systems, reciprocity, collaboration, public *** knowledge, culture, value systems, ethics, environmental governance and sustainable development. These elements constitute a complete globalized social system through which humanity needs to build a sustainable future.

These 12 systems are bridges and links between people and various aspects of the environment, culture, economy, politics and society. In the context of globalization, the interactions and impacts among these elements are more complex and profound. For example, environmental issues are not only an ecological issue, but also involve economic, political and social aspects. Therefore, we need to recognize the relationships and roles between these systems in order to better understand and solve real problems.

Facing up to the 12 systems can help us better establish and maintain a social system for global stability and sustainable development. We need to take into account the complexity and interconnectedness of these systems in realizing sustainable development, so as to develop more comprehensive, scientific and feasible solutions. Only by harmonizing the various elements can we advance the goal of sustainable development on a global scale*** together.
