Tourism is good and bad at the same time
There are always two sides to tourism. The upside of tourism is that it stimulates authorities to preserve nature. The downside is lots of travelers causing pollution and contributing to global warming. The Alps are very sensitive to global warming. As a tourist, you can enjoy the Alps while helping to protect them too.
5 easy things you can do to protect the Alps
Here's what you can do to protect the Alps while you visit Switzerland. You'll help fighting global warming and prevent pollution:
Traveling to Switzerland: if you can, avoid traveling by plane or car. Choose the train. If you can't, you can compensate for the CO2 emission of your trip. If you fly, take a non-stop flight if possible (most fuel is burned during take-off and landing);
Traveling in Switzerland: use public transport instead of a car. The Swiss train system is one of the best in the world: clean, safe and comfortable. If you prefer to travel by car, please compensate for the CO2 emission;
Food: buy local biological products. That's quite easy in Switzerland as many supermarkets offer a wide range of these products;
Drinks: do not buy bottled water. Swiss tap water is just as good and results in a much smaller CO2 footprint;
Try to separate waste whenever possible.
Most of this can be applied to any holiday, and even to your everyday life. Of course there's much more that can be done, but this is a good start. Many thanks for being a responsible traveler!
