Les Trois Vallées, an enormous ski area in France that stretches from Val Thorens to Les Menuires and Courchevel. With over 600 kilometers of ski slopes, 180 ski lifts and an altitude ranging in between the 1800 and 3230 meters, the mountain area is popular all over the world. However, when the snow melts in the spring, what is left behind is a huge amount of waste. Last year, more than 6000 volunteers collected 65 tonnes of waste from the different ski areas.
