The 100-km wilderness hike attracts so many visitors from around the world that vegetation and wildlife along the trail is dwindling. And in the name of ecological and cultural tourism some truly ugly things can happen. The government of the Southeast nation of Laos has approved a Malaysian Corporation's plan to build a huge 'eco-resort' on 18,500 hectares of national parkland. As it is now, many communities surrounded by the natural wonders tourists pay to visit enjoy few advantages of that visit. Back in Nepal, only an estimated 7 cents per dollar spent by trekkers stays in the country.
Tourism can be ethical, even invaluable, but it often depends on the individual tourist.
Just like any product or service you buy, you have power as a travel consumer. Stay at locally-owned hotels, eat at local restaurants, use local guides and services. Make your money work in the regional economy as an incentive to protect the surrounding natural heritage, rather than allow your dollars to leak out beyond local borders. Get acquainted with local customs and respect them. Travel in a spirit of humility and with a genuine desire to meet local people.
