The term "ecotourism" was first proposed by the World Conservation Union (IUCN) in 1983. In 1993, the International Ecotourism Association defined it as: tourism activities that have the dual responsibility of protecting the natural environment and maintaining the lives of local people.

The connotation of eco-tourism emphasizes the protection of natural landscapes and sustainable development of tourism.

Ecotourism was first proposed in 1983 by Ceballas Lascurain, a special advisor to the International Union for Conservation of Nature (IUCN).

At that time, two key points were given about eco-tourism. One is that the objects of eco-tourism are natural scenery; the other is that the objects of eco-tourism should not be damaged.

In the context of the environmental crisis facing human beings around the world, with the awakening of people's environmental awareness, the green movement and green consumption have swept the world. Ecotourism, as a green tourism consumption, has caused huge repercussions around the world as soon as it was proposed, and the concept of ecotourism has rapidly become popular.

To the world, its connotation has been continuously enriched. In view of the current deteriorating condition of the living environment, the tourism industry starts from one of the key points of eco-tourism and defines eco-tourism as "return to nature tourism" and "green tourism";

Due to the various environmental problems that have arisen in the development of the tourism industry, the tourism industry starts from the second key point of eco-tourism and defines eco-tourism as "protection tourism" and "sustainable development tourism".

At the same time, countries around the world carry out eco-tourism according to their own national conditions and form unique eco-tourism.

Western developed countries with better development of eco-tourism first recommend the United States, Canada, Australia and other countries. The eco-tourism objects in these countries have shifted from cultural landscapes and city scenery to Shebelos.

The "natural scenery" designated by Laskeri is to maintain relatively primitive nature. These natural scenery are positioned as national parks with excellent natural ecosystems in their country, and as excellent ecosystems dominated by virgin forests abroad.

This has made many developing countries become eco-tourism destinations, among which the Caribbean and African safari parks have become eco-tourism hot spots.

According to estimates from the World Wildlife Fund, in 1988, tourism revenue in developing countries was US$550 billion, of which ecotourism was US$12 billion.

In Costa Rica, almost half of the international tourists received every year are ecotourists who go to enjoy the tropical rainforest.

According to statistics from the World Tourism Organization, the number of international tourists to Africa in 1994 was 18.5773 million, of which ecotourists accounted for a considerable proportion.

In Western developed countries, traveling to nature on weekends and holidays has become a fashion.

Western developed countries attach great importance to the protection of tourist objects in eco-tourism activities.

In the development of eco-tourism, avoid large-scale construction projects and other practices that damage the natural landscape. Tourist transportation is mainly on foot. Tourist reception facilities are small and hidden among trees. Most accommodations are tents and camping. Every effort is made to maximize the impact of tourism on tourist objects.

Impact is minimized.

In eco-tourism management, resounding slogans such as "leave only footprints and take away only photos" are put forward to protect the environment, and some eco-tourism destinations are set up to explain the mysteries of nature and protect nature that is closely related to human beings.

The signage system and popular tourism activities allow tourists to enhance their environmental awareness while enjoying themselves, making the eco-tourism area a natural classroom for improving people's environmental awareness.

In the past, Western tourists liked to go to tropical seasides for leisure and vacation. The unique warm sunshine (Sun), blue sea (sea) and comfortable sandy beaches (Sand) unique to tropical seasides made living in Western developed countries with serious pollution and fierce competition a

Tourists' bodies and minds are calmed, and the "Three Ss" have become the most attractive tourist destinations that Westerners yearn for.

With the development of eco-tourism and the increase in tourists' environmental awareness, the tourist hotspots of Western tourists have changed from the "three S" to the "three N", that is, going to "Nature" to remember the "human beings once lived in harmony with nature".

Nostalgia (Nostolgia)" complex allows one to enter "Paradise (Nirvana)" when immersed in nature. The highest spirit emphasizes the protection of natural landscapes and sustainable development of tourism.
