This video introduces the Metacoupling framework, proposed by Professor Jianguo "Jack" Liu, as a new way to understand human-nature interactions in a highly connected world. Through examples such as food trade, pollution transfer, global crises, migration, tourism, protected areas, and social change, the video shows how actions in one place can affect people and ecosystems nearby and far away. By examining intracoupling, pericoupling, and telecoupling, metacoupling reveals hidden connections across regions and scales and offers a powerful perspective for sustainability research and decision-making.
