"Warning signs" are indicators that something may be wrong or that caution is needed. They can be visual, such as traffic signs that alert drivers to potential hazards, or they can be behavioral, like changes in a person's mood that suggest emotional distress. Recognizing these signs can help prevent accidents or address issues before they escalate. In various contexts, warning signs serve to protect individuals and communities. For example, in healthcare, symptoms like persistent pain or unusual fatigue can signal underlying conditions. In environmental science, changes in wildlife behavior may indicate ecological problems. Being aware of these signs is crucial for timely intervention.
