However, the ski slopes where not that unique. To be honest, I doubt whether it was worth making accessible the glacier. Destroying one of the Alp's last glacial regions seems a big price for some more ski-drivable weeks a year... I don't feel like abolishing skiing, I just wished alpine tourism would be sustainable.
Grenoble in my opinion has taken an important step: there are driving normally scheduled public-transit busses directly to the skiing regions in reach. So accessing the Alps by public transport, and only when it is skiing season is a part of sustainable tourism. Everbody can contribute his or her part to sustainability: ?to everything there is a season?, ecclesiastes 3:1-8. Der Umkehrschluss ist zul?ssig. (So in reverse). Sorry, I find no better way to express the same in English. Sometimes you just can't replace your mother tongue.
