意大利冰川穿上"防晒衣"
Glacier covered with tarpaulins A team of conservationists has begun the process of laying vast tarpaulin sheets to cover over 100,000 sq metres of the Presena glacier in Northern Italy to prevent it from melting due to global warming. The sheets, which measure 70m x 5m, are sewn together and bags of sand are placed on them to weigh them down. The six-week process is repeated every year once the ski season is over and summer begins in full force. The conservation project was first undertaken by Italian firm Carosello-Tonale in 2008 - at which time only 30,000 sq metres of the glacier was covered. The process of removing the protective tarps will begin in September, and will take another six weeks. Since 1993, the Presena glacier has lost more than one third of its volume. |
