1. The International Ecotourism Society (TIES) defines ecotourism as "responsible travel to natural areas that conserve the environment and sustain the well-being of local people."

2. Responsible tourism observes basic eco-ethical tenets. Fundamental rights like the right to exist or to live in peace, right to pure air and pure water are basic rights even for wildlife, indigenous people as well as for nature as whole.

One step forward in ecotourism is to get involved in eco-restoration, biodiversity restoration and eco-development of local people in any degraded tourist ecosystem. 

4. India, with her kaleidoscopic ecosystems and a wealth of cultural heritage of great antiquity has immense scope for ecotourism. Constant research to identify newer areas and spots for eco-tourism, preparing brochures on them and on the eco-ethics relevant to each, organising environmental trails and training knowledgeable guides, preferably using the services of the local people are the obligations of the tourism department.
