tourism Tourism has been seen as an important industry and has brought unprecedented opportunities to these countries. However, many fear that tourism threaten environment and local life.I would like to discuss pros and cons of tourism as follow. Promoting the development of tourism is not without its criticism. A main problem associated with tourism is that unchecked growth of construction of infrastructure and tourism facilities(such as airports, roads hotels and resorts)are putting considerable pressure on environmental protection. Making improvement of tourism industry ,regardless of environment cost, is linked to natural habitat loss,soil erosion, deforestation and increased pollution. Posing a threat to local culture is considered as another problem. In order to get rid of poverty, an increasing number of local people abandon their traditional livelihoods and start to work in the tourism industry. Furthermore, a staggering number of local residents uphold that tourism ,especially international tourism,has a negative effects on their lives. Disturbing local people’s lives and putting strain on daily necessities are regarded as two factors which arise from that tourists are flocking into local community. These factors combine to create a situation that local people don’t embrace tourism with open arms. Its downside may deserve our attention, but we should acknowledge that our society has benefited a lot from developing tourism industry. Firstly, tourism is seen as a dominant industry in a growing number of developing countries.;it plays a big part in generating enormous employment opportunities and increasing foreign exchange earnings,which offers an important routes out of poverty. Moreover, due to reap economic benefits,the authorities are able to invest more money in establishing infrastructure and lift people’s standard of living. As indicated above, the travel industry, from any angle, is huge and beneficial, although these countries need to accept social and environmental cost.
