Video shows traffic jam on Everest as record numbers attempt the climb

Mount Everest's highest campsite has been transformed into a garbage heap, with a video showing abandoned tents, empty oxygen bottles and human waste littering the snow. Footage published on social media shows Camp IV, the highest campsite on Earth, full of piles of rubbish left behind by climbing groups, with scores of worn-out yellow tents flapping in gale-force winds.
