A summer clean for the mountains
On a summer hike in some winter ski areas there is more 0 likelihood of spotting drink cans and other litter discarded by skiers than mountain flora and fauna. Huge quantities of rubbish are slowly 17 as the snow melts. Because much of the litter is non-biodegradable, the amount is increasing. Plastic bags, bottles and cans, dropped by anonymous 18, are just some of the examples found on the mountain sides. It’s hard to view the task of cleaning it up with anything other than 19.
In an attempt to counter this, 20 resorts are now appealing to skiers to return in the summer and participate in mountain-cleaning days. These have been 21 introduced at weekends, when organisers can capitalise on the 22 of mountain areas with hikers and mountain-bikers, who will boost the turnout.
These days are sociable and fun, 23 those who take part to do something worthwhile. In some cases, up to 5 kilograms of litter can be gathered by each volunteer leaving the organisers with a ton of rubbish to be prepared for 24. In return for their help, litter-pickers are often treated to a barbecue at the end of the day.
