Recently, a safety accident occurred due to illegal outdoor crossing. Five people illegally crossed the Aotai Line in Shaanxi, and three people unfortunately died. The sudden disappearance of fresh life is lamentable and once again sounds a heavy alarm: when "exploring nature" becomes indifferent to rules, and when "challenging oneself" evolves into a gamble on life, such "willful" crossing must come to an end. In recent years, safety accidents caused by illegal crossing have emerged one after another, and relevant departments have issued frequent warnings. However, under the influence of traffic, "secret crossing" has been packaged as a game for "brave people". Some people simplify professional exploration as a "spontaneous travel", while others blindly trust personal experience and ignore professional warnings. In fact, the reason why the so-called "secret realm" is rarely visited is because the environment here is complex and the risks are unpredictable, making it unsuitable for non professionals to enter and exit. Every illegal crossing may be risking one's own life and putting rescue personnel in unknown danger, which is irresponsible to oneself, one's family, and society. The tragedy has already occurred, and the alarm must be sounded long. On the one hand, relevant departments should strengthen the management of protected areas, increase the cost of illegal and irregular activities, and make "eager to try" truly feel the cost of illegal crossing. On the other hand, responsible entities such as online platforms should remove negative inducements aimed at "attracting attention" and "earning traffic", and actively promote healthy and rational outdoor sports concepts. More importantly, every outdoor enthusiast should establish a sense of awe, both for the magnificence and unpredictability of nature, and for the precious uniqueness of life. (New Society)
