摘要：As the traffic of tourists increased in a particular area, it was observed that environmental and ecological balances were disturbed due to over commercialization. The scenic beauty was made more ‘customer friendly’ and the natural tourism products more accessible and ‘saleable’ by man. Environmentalists are agitated about the damages and carelessness showed by the tourists. Culturally and socially, tourism can impact the destination country, but its effect cannot be solely attributable to simple tourist activities. On the road to development, tourism products have also witnessed some changes. As the world changed and developed, new necessities were identified. As people became more aware, the needs changed and new tourism products were developed to satisfy these new found needs. The last few years have seen the emergence of new areas in tourism like, special interest tourism, green tourism, eco tourism, social tourism and so on.
