What is a critical threshold?

A critical threshold refers to a specific point or limit at which a significant change occurs in a system or process. Crossing this threshold can lead to drastic shifts in behavior, stability, or function, often resulting in irreversible effects. In ecological contexts, for example, it might denote the point at which an ecosystem can no longer recover from disturbances. Understanding critical thresholds is essential for effective management and mitigation strategies in various fields, including environmental science, economics, and health.
