In week 11, Dr. Kellee Caton told us ecotourism and Transformation as the guest speaker. Dr. Kellen told us that nature has been commoditized, because nature is sold to customers as a tourism commodity so that customers can experience nature, and ecotourism can promote the welfare of wildlife, and ecotourism can create good results for the community among tourism operators, tourists, and the host community, and also improve indigenous recognition. People’s relationship with nature has become more and more abstract. People are less and less appreciative of their existing homes. As a result, the land, the sky, and the sea have been destroyed. The duality of nature and culture shows that human beings are independent of other things, which are composed of different things, civilized things, rather than the wild things of nature. The most important value of ecotourism is to make people re-establish the relationship with nature, make the relationship between people and nature no longer abstract, and arouse the charm of nature to human beings, so as to bring greater benefits to all living things in nature.
