Since the 1970s, humanity has been using more resources than the Earth can renewably provide in the same given year. Simply put, the Earth is in ecological debt - and that debt continues to grow every year. What are the drivers? What are the impacts beyond the environment? What is Asia's ecological situation, as well as Japan's? Most importantly, what can be done to reverse these trends? The Global Footprint Network is an international think tank working to create a sustainable future through the Ecological Footprint, a resource accounting tool that measures how much nature can provide, how much is used, and who uses what.
