One of Switzerland\'s most popular skiing areas has been covering mountain areas with cloth material in an effort to reduce ice melting over the summer. Workers have placed large blankets of material around Mount Titlis, a skiing area near the Swiss mountain town of Engelberg. The area contains a glacier that has been losing large amounts of ice over the past 20 years. The protective cloth, made of polyester (聚酯纤维) material, is designed to block the sun.
