Mount Everest, Nepal/China

Mount Everest commands attention as the planet's tallest point at 8,849 meters, yet its majesty is shadowed by overcrowding: over 800 climbers attempt the summit each season. Outperforming #8 Paricutin Volcano in vertical scale by over 8,425 meters, Everest's perilous allure generates more than 5 tonnes of waste annually, threatening its pristine environment. This data underscores a stark reality where natural splendor clashes with climbing ethics, as the mountain draws 40% more expeditions than the average Himalayan peak.
