Recently, a video of tourists scattering paper on the grassland has sparked a heated discussion on the internet. According to media reports, in the video, several men and women stand in a row holding pieces of paper, letting them scatter in the wind. There is also someone holding a mobile phone in front to take photos. The location of the video account shows that the filming location is on the grasslands of Hulunbuir, Inner Mongolia. This behavior quickly sparked questions from netizens: "Isn't this polluting the environment?" A staff member of the Hulunbuir Municipal Bureau of Culture and Tourism said, "When traveling on the grasslands, one must not litter with household waste casually." This move is suspected of damaging the grasslands and needs to be reported to the forestry and grassland department. A staff member of the Forestry and Grassland Bureau of Hulunbuir City said, "Tourists from other places throwing garbage indiscriminately is suspected of damaging the grassland ecology, and this is under the jurisdiction of the Grassland Supervision and Management Department." Currently, relevant departments are verifying the specific location of the incident and handling the matter. Laws and regulations will clarify attitudes. However, the sight of tourists dancing and cheering in the video is quite dazzling. As claimed by the video publisher, this is' recklessly spreading on the prairie ', and even a hint of' knowing it's impossible to do it 'can be heard in the words. 'Do not litter everywhere' is a basic common sense in a civilized society. Why do we easily forget the rules of civilization when we go to the grasslands? The tourist's statement is that the scattered paper is made of "biodegradable" material. Seemingly 'controllable consequences', but how long does degradation take? What conditions do you have? What are the explicit or implicit effects of degradation products on grasslands? A series of questions have not yet been scientifically verified. It must be clarified that 'degradable' does not mean 'pollution-free'. This unfounded defense of "harmless materials" and the cognitive thinking of "destruction before restoration" are worthy of people's vigilance. Compared to direct destructive behaviors such as littering and crushing grasslands, this casual mentality disguised as "science" is even worse. In recent years, it has been common for people to lie on the tracks or step on protected areas for the sake of a photo or a video, disregarding life safety and ecological protection. With the deep interweaving of check-in culture and tourism culture, tourism scenes are increasingly presenting complex and diverse social aspects. For those destructive behaviors that cross boundaries, clear punishment is needed to make people aware of the fragility of the ecological environment. A netizen said, 'Let them pick up the pieces of paper one by one.'. Previously, some netizens suggested punishing tourists for racing and drifting on the grasslands and adding them to the blacklist of scenic spots. These suggestions, although informal punishments, are quite enlightening. After all, the follow-up work of cleaning up the site and restoring the ecology after "reckless scattering" cannot rely solely on the self repair of the local and grassland ecosystems in Hulunbuir. After 'recklessness', one must' hit the wall 'in order to make the disruptors aware of the bottom line of civilization. Grassland is like a thin blanket covering the earth, with drastic seasonal changes that make it difficult for animals and plants to adapt to drought. The ecosystem is sensitive and delicate. Although it has the tenacious side of "Lush grass on the plains" in poetry, it does not mean that we can trample and pollute at will. Facing nature, we must ultimately maintain a sense of awe and guard the boundaries of harmonious coexistence between humans and nature. (New Society)
