Though it may sound incredible at first, yet it is true: there is great mess on Mount Everest. The authorities have declared that from now on climbers aiming to conquer the world highest peak must also carry with them a sack for collecting rubbish in addition to the climbing gear, sleeping bag, and hot and cold foods. Previously, these sportsmen did not concern themselves with this matter, and as a result the popular base camps on the mountain are disfigured by discarded cans, empty oxygen tanks and other articles. Similar regulations have come into force for the polar regions, which also have become increasingly full of rubbish over the last years. Therefore the basic rule is: those who intend to conquer nature must also think of its protection!
