Abstract

Ecotourism is a new trend in tourism industry. Beautiful landscape and natural views are the focal points and tourist-attraction points of this tourism. Thus, it is necessary to consider the importance of its role in environmental preservation to achieve a sustainable development. Although, the relative importance of ecotourism is still lower than collective or traditional tourism, it is gaining an increasing validity and reliability in some countries. Ecotourists travel to natural and genuine parts of earth and gain valuable experiences for their own motifs. They join to nature preservation and friends groups after getting insight on cultural-environmental aspects of the nature of each region and country. The certain fact is that tourism activities influence environment and to prevent or control negative effects on environment. The policy makers and planners should predict basic needs of tourists on one hand and think of the positive and negative effects of tourism on the other hand, when preparing detailed and comprehensive plans.
After long years of makind’s life in earth, the natural landscapes and sceneries are exposed to the dangers and risks resulted from human activities. To confront this increasing risk and danger, an urgent need is felt in global level to make people aware of the importance of preserving natural resources as a critical issue and to start a new movement to obtain active participation of people, particularly local people of any region to preserve natural resources and landscapes and present it as a tourist goods. The World Tourism Organization; too, recognizes sustainable development as an activity that not only preserves natural and cultural resources, but also increases the capacity to create job and earn income
