The tourism industry is a clear positive impact in terms of the economy, also have negative impacts on all aspects of life in Bali. The negative impact is most keenly felt by residents of Bali is the destruction of the environment and cultural changes.

Bali as a world tourism destination, facing a difficult situation and in doubt, due to the negative impact of the tourism industry. Globalization makes people tend to be human individualist and consumerist impressed, so trying to get what it needs to process natural resources without regard to environmental sustainability. This is causing many environmental problems faced and have a negative impact on all sectors, ranging from the industrial sector and the tourism sector. Pollution and contamination is one of the negative impacts and become like a tradition that is always there in the corners of the city. Damage to the environment is also an impact on the flora and fauna because their habitats are disturbed so that makes shortages for some populations. The tourism industry can provide positive and negative impacts for Bali.

The negative impact on the tourism industry is the rapid growth of property development. Thus, the area of forest cleared for tourism facilities, it has an impact on the preservation of the environment in Bali. If the entire forest area is cut down and used for tourism purposes as well as the exclusion of forest functions, will bring negative impact is very bad for the life of the Balinese people, such as floods and landslides. So that although the purpose of development of tourism facilities, but the negative impact this can certainly be a boomerang deadly for Bali tourism.
The negative impact resulting from the tourism industry in Bali's most visible is conversion. Expanse of agricultural land has now turned into buildings, villas, shopping malls, and hotels, built with the override function of the land. Many of productive land were transformed to enable just for tourism development. Just look at the tourist area of Ubud, Gianyar Bali as well as the southern region, and other places in Bali. Many tourist attraction built by utilizing the productive land. Not only that, the development of tourism often displace or disrupt the presence of the holy places. This is an increasingly implies that the progress of science and technology in this era make more and more people are guided by the interests of each and the race for profit as much as possible and ignore the environment in which we live. Not only that, people also further eroded the moral and cultural values in the building of tourism facilities so that the exclusion of the customs and cultures and beliefs held by citizens of the Balinese.

Changes over the function of productive land for agriculture, are now mostly used for construction of uncontrolled and unsupervised well. These conditions have a negative impact on the environment, also have a negative impact on flora and fauna. The decreasing availability of land and a place to live for wild animals and many of them became angry, and evacuate to a safer place, and then create new problems by the animals. If the physical development of tourism only promote the beauty and the exclusion of environmental sustainability, the impact is not only on environmental pollution alone, also can disrupt ecosystems. Tourism development which also does not pay attention to public confidence in Bali, will cause a negative impact to the survival of the citizens of the Balinese.
Any damage and environmental problems that occurred in Bali is one of the negative impact caused by the absence of rules which strictly regulates the layout of the development of tourism in Bali. As well as law enforcement officers are unprepared in meninkap violations occurred. However, Bali Clean and Green program launched by the provincial government of Bali is a significant step as an attempt of the government to overcome the environmental pollution. In addition, the support of the community is very important to realize the program of the government for survival together. Society should not be easily affected by the lure of money on tourism development is not systematic, thus causing damage to the local wisdom and balance reduced.
A systematic environmental management and integrated carried out to preserve the environment and prevent pollution and environmental damage. Balancing trust and local knowledge is a key point that a government priority and the citizens of the Balinese in maintaining harmony with God, fellow human beings, and the environment as part of the successful implementation of the development of tourism and the environment in Bali.
