When performing high-altitude tightrope walking, not using a safety net will significantly increase the risk of multiple dangers, mainly including the following aspects: 1. **Falling risk**: Without a safety net as protection, once the performer slips or loses balance, he may fall directly to the ground, causing serious injury or death. 2. **Psychological pressure**: The lack of a safety net may increase the psychological burden on the performer, easily leading to tension and anxiety, which will affect his concentration and performance and increase the possibility of accidents. 3. **Environmental factors**: The high-altitude environment is often unpredictable, such as wind speed and temperature. Without a safety net, any environmental changes will directly affect the safety of the performer. 4. **Equipment failure**: Any failure of the wire rope or supporting structure may lead to serious consequences. Without the protection of a safety net, once there is a problem with the equipment, the consequences will be disastrous. 5. **Crowd gathering**: High-altitude performances often attract the attention of the audience. If there is no safety net, it will also produce a greater sense of excitement for the audience, which may lead to unexpected behavior or interference, thereby increasing the risk of performers. 6. **Unexpected interference from animals or objects**: When performing at high altitude, there may be unexpected interference from birds or other objects. Without a safety net, the performer may lose balance when dealing with emergencies. In summary, not using a safety net will undoubtedly greatly increase the danger of high-altitude tightrope walking performances. Protective measures are the key to ensuring the safety of performers.
