Cans will remain in nature for thousands of years

Rivers, which originate from the snowy slopes of Alborz once attracted people to see the beauty of nature, now have become the streams of raw sewage and unsightly garbage. The nature becomes stronger than the human. The headwaters are still beautiful and it is a wonderful gift. But far from the headsprings, although the water is flowing, it is not clear anymore, the father down you go, the darker the water has become. If you want to wash your face and refresh yourself, you must watch out for a sardine can or a piece of glass, or if you want to drink some water, it is enough to pour some water in a glass to find a piece of plastic in there.

Dear fellow traveler:

Unfortunately the garbage of the alpinists' shelters business establishments along the trail are dumped in the valleys below.

Today, we bring back our garbage to the city. We don't permit picking the flowers or breaking the branches of trees, today we respect the nature.

Cans will remain in nature for thousands of years
