Italy covers melting glacier with reflective sheets

The video discusses the use of geotextile sheets on the Presana Glacier in Italy to prevent snow melting. These sheets, applied since 2000, reflect sunlight and help conserve about 70% of the snow during summer. Covering 120,000 square meters, the task takes up to six weeks. The glacier has shrunk by a third since 1993 and faces additional melting risks due to algae that absorb sunlight.
