What is one of the three important survival needs mentioned in the context?

The concept of survival needs emphasizes the essentials required to sustain life in emergency situations. Among these needs, signaling is crucial for alerting rescuers and communicating your location. This function can be vital in wilderness or survival scenarios, as it directly relates to the ability to be rescued.

While food, water, and mapping are also important in survival situations, the immediate need for signaling can be the deciding factor in whether an individual is found and helped in time. Knowing how to create signals—such as smoke, reflective surfaces, or sound—can significantly increase one's chances of survival by ensuring that they become visible to searchers.
