How Not to Fall Off a Cliff, or, Using Tipping Points to Improve Environmental Management

Abstract

Three decades of study have revealed dozens of examples of natural systems crossing biophysical thresholds (or “tipping points”) as a result of human-induced stressors, dramatically altering ecosystem function and services. Environmental management that avoids or reverses such tipping points could prevent severe social, economic, and environmental impacts. Here, we attempt to demonstrate the desirability of, and opportunities for, environmental management using thresholds under U.S. federal law. We find that conceptually, tipping points can and do guide some regulatory decisions. However, explicitly focusing a larger set of environmental rules on avoiding
