Tourism in the Himalayas

First of all, lets begin with the history of tourism in the Himalayas which is home for the worlds highest mountains."The Himalayas is about 1,500 miles (2,400 km) long and about 100 to 150 miles (160 to 240 km) wide." Tourism in the Himalayas started in 2nd century BC with pilgrims coming from other parts of the world for the worshiping of holy rivers and the nature deities. The second stage of tourism began in the 19th century, when the British discovered the Himalayas as a recreation area. Likewise, the modern tourism was started in the 20th century. In addition, mass tourism in the Himalayan region started in the 1950's after Sir Edmond Hillary and Tenzing Norgay climbed the Everest and made the region popular around the world.
The Himalaya, in Asia, is the highest mountain system in the world.
Today due to tourism,  the Himalayan regions had an enormous influence on the economy.  But on the other hand, the environmental impact caused by  tourism is clearly visible and massive. The Himalayas is  described as a fragile ecosystem, where ''forces of ecological degradation is building so rapidly and visibly.'' Today, the Himalayan regions are facing problems such as deforestation, waste management, pollution,  trail degradation and so on which are caused by tourism activities directly or indirectly. Therefore, in the coming posts, I'll get deeper into the environmental issues caused by tourism in the Himalayan regions which are a serious problem.
