What are some environmental issues Mt Everest is facing?

Mount Everest and the surrounding areas are facing severe deforestation due to the increase in tourist traffic. Pollution from poor waste management facilities taints the local water supply. On Mount Everest itself, trash has become a serious problem. The mountain has been given the nickname "the world's highest landfill." Discarded oxygen bottles, tins, medical syringes and bottles, tents, and corpses litter the mountains' most popular routes, particularly the South Ridge.
