Around the world, disastrous effects of earthquakes, floods and droughts are painful evidence of our continuing struggle between human resource demands and the sustainability of our ecological systems. "Too much or too little" is often deemed the culprit in these crises, focusing on our "lacks and needs" instead of exploring the mechanisms of the functions and processes that sustain us. Through a unified approach to the preservation and management of our human and natural resources, the flows of nature that connect all communities can serve as a basis for the maintenance and protection of our valuable ecosystems.
