Warnings from ecologists about environmental damage around Mount Everest have been ignored for years. Campaigners warn that tourism has negatively impacted the area through waste and development. While tourism provides income for local communities, an environmentalist explained it places strain on resources and estimated only 10% of tourist money reaches local economies. Sherpa guides who lead climbers oppose limiting permits as many locals solely depend on tourism for income. However, Nepalese officials have no plans to close Everest as climbers provide significant funds.
