"For decades, people's attention has always focused on garbage in base camp near Everest and on annual" cleaning expeditions. " Basically this is what I call the cosmetic cleaning, as it can be easily taken and executed. The real problem lies in the huge tons of plastics, beer cans, whiskey bottles, steel food containers and other solid waste imported by the owners of the houses. They import it to meet the needs of the hundreds of thousands of tourists who now visit the park annually.
For the locals, this is "combustible trash", and the owners of the houses dump it in places for burying, where they burn it, when it accumulates, and bury it. Pits under the trash can occupy an area of 25 to 200 square meters, while their number in the park can be more than a hundred. The problem is that when it is burned, toxic poisons are emitted into the air, and buried and burned garbage does the same with groundwater."
