Who cares about glaciers? Some mountain enthusiasts, skiers, hut keepers, alpine pastures. A few paths become impassable - so what? The high alpinists can also go somewhere else
hiking. A few alpine pastures are endangered by the threat of mudslides - sheep and cows can also be kept in valleys. Some species of flowers and animals will disappear - but others will follow. A few huts will have drinking water problems - these can be safely closed.
