There are both positive and negative effects resulting from tourism.Positively it creates employment and economically enables the conservation of valuable space;restrains a migratory tendency within the home population improving their socio-cultural education.It encourages support of local commercialisation resulting in the free interchange of ideas,customs and sensitization of issues concerning the eco-environment.The reduction of working hours,the ever present threat of unemployment because of technological advancement and the globalisation process enables the tourism industry to provide an interesting and stimulating intensive alternative.

Just as significant are the effects of the rising cost of natural resources,water,energy.The spoiling of landscapes with land reclamation;rising levels of waste disposal;alterations to ecosystems;the extinction of rare species of animals and plants;the loss of traditional values and rising levels of prostitution,that is sex tourism.There is the narcotics trade,forest fires,together with the rising cost of housing.

There are rising levels of carbon dioxide and other contaminating gases from increasing frequencies of airflights with ozone erosion and acid rain.All kinds of ecosystems are becoming affected.Thailand is littered with golf courses that consume large amounts of pesticides and water.There is hardly anywhere in the world not affected by tourism impact .Tourism is an aspect of globalisation most sensitive to any repercussion.In the eastern region of Spain for example,Benidorm has a great concentration of hotels,accommodating nearly half a million tourists in August within an area of little more than 12 kilometres.There is also a large proportion of the population of many countries who do not participate in tourist flows but who nevertheless will become part of such flows with the emergence of new markets in Latin-America and Asia.
