The least impact rule of outdoor environment LNT rule

With the continuous development of outdoor activities in China, outdoor activities with outdoor hiking, camping, rock climbing and rafting as the main contents have been increasingly accepted by people of all ages as a fashionable fitness project, and the outdoor population tends to be diversified and popularized. However, due to the uneven understanding of environmental protection, the contradiction between outdoor activities and environmental protection has also increased.

How to change this contradiction and make outdoor activities in China move towards the road of benign development? Here, we will introduce an important law that has long been recognized and implemented in outdoor activities-the law of minimum impact of environment, which is called LNT law for short.

In the United States, the population engaged in outdoor activities increased sixfold from 1965 to 1994. According to the survey conducted by the Outreach School, in 1965, 9.9 million Americans engaged in hiking activities, and by 1977, the number had increased to 28 million. In this development process, there are also some problems existing in outdoor development in China at this stage. Alpine lakes are polluted by human waste; Some trails are eroded to the knee; The camp has become barren, and garbage of all sizes can often be found. This phenomenon puts land managers in a dilemma, because they have to meet the needs of tourists and try to protect the natural environment.

in the early 198s, the initial LNT course of American forest department began to be introduced to other outdoor activities courses.

When closing some overused areas; Carrying capacity control; And limiting specific camps to become an important management tool for land managers, environmental education for tourists is actually a more effective solution. Numerous low-impact environmental education courses are taught in land management units, and slogans such as "What you carry up the mountain must be carried down the mountain", "Tread lightly on the land" and "Only take photos and leave footprints" are familiar to many hikers.

in 1994, a non-profit organization headquartered in Boulder Colorado, Leave No Trace, Inc. was responsible for coordinating the work of all LNT units, issuing licenses and raising funds, and its perennial operation and correct guidance. The law of minimum environmental impact (LNT law) has also become an important guiding principle widely followed by outdoor enthusiasts and has been continued.

1. Plan ahead

Any outdoor activities need to be prepared in advance, understand the rules and regulations on environmental protection at that time, make adequate preparations for possible situations, and choose suitable equipment according to the learned situation. At the same time, we should fully understand the route characteristics of the activity area and design the travel route and campsite in advance accordingly. According to the actual situation of the line, plan the quantity of food carried, and then simply handle the food, which can be unpacked and packaged as much as possible, and reduce the generation of garbage as much as possible. Simply put, planning and preparation in advance should be: not blind, not illegal, not wasteful and prepared.

Second, we can tolerate ground travel and camping

In outdoor activities, sometimes we often choose disorderly cutting to reduce the distance and difficulty, which is not desirable. The LnT law stipulates that whenever and wherever possible, walk on the existing trails, without taking shortcuts or going straight up and down, and the team will only take a single route when marching. If the road conditions are good and the backpack is not too heavy, you can consider soft-soled shoes to reduce the impact on the ground.

When hiking on non-hiking trails, you should choose places that can tolerate human trampling, such as bare rock or gravel slopes. In such areas, scattered walking is the best choice to reduce the impact on the environment.

The choice of campsite is very important in camping activities that have a great impact on the environment. Generally, we will require the campsite to be located more than 5 meters away from the water source to eliminate pollutants. In the popular route, only camp on the existing camp with hard soil and no grass, and concentrate camp activities on the areas that have been hit. If you are in an area where there is little human activity, put the camp in a place that has never been used, not in a place that has been slightly impacted. Camp in the existing camp with obvious traces, and sometimes there are traces of fire on the existing camp. If it is a frequently used camp, the surface is seriously eroded and the roots are exposed, you should choose other places to camp and give the camp a chance to rest.

The most suitable places for camping are rocks, gravel and sand, because they are very tolerant of human trampling. Other good choices are hay fields, while forest fields with rich vegetation and leaves on the surface are less tolerant of human impact.

Third, properly dispose of garbage

"Everything that goes up the mountain must be carried down the mountain" is an important principle, which keeps the original appearance of the campsite and embodies the most basic quality of campers. It is accepted that the disposal of excreta can be buried in a cat hole 1-2 cm deep and at least 6 meters away from the water source, camp or trail. Think carefully about the problem of toilet paper. Nature provides many environmentally friendly ways. If you must use toilet paper, you have to carry it down the mountain, which is necessary for us to pay attention to.

when dealing with food waste, we try to reduce the packaging before we leave, and at the same time, we try to use reusable utensils as much as possible, and plan the appropriate amount to avoid waste. In camping activities, use cleaning products as little as possible, and do not wash your face, brush your teeth, wash clothes or wash vegetables directly in the water source. Sewage is poured into a pit more than 5 meters away from the camp and water source and 25-3 cm deep. All the food residues should be taken away, even some degradable foods such as stone and peel must be taken away. The least impact rule of outdoor environment LNT rule 2
