Tourism development: the development of large-scale tourism often requires the participation of central government which alone has the power necessary to improve the international competitiveness of the popular tourist destination for loq ue often must offer significant concessions. In addition are the only ones able to obtain tourist allocations of funds from the UN or other governments. Control legislation: creating laws regulating tourism activities, especially in health, taxation, etc.. Monetary control of capital into and out of the country. Health control: controlling for vaccines that are required to visit certain countries and which require them to citizens of country risk.Measures to protect the environment: current economic consciousness of governments has led to continued protection of the environment, because nature is the raw material for tourism and if not careful will negatively affect future tourism. Public Administrations are developing sustainability policies to ensure orderly planning that respects the ecological chain. There are also other socio-political effects not exclusively related to the control of public administracioens. Technological effects: those receiving societies of tourist flows in general benefit of all technological advances may be requested by visitors. Political effects: tourism can exercise some influence in the politics of a country as its poor international image can affect tourist flows. Social impact: the massive influx of tourists can cause rejections of certain cultures or races.Environmental effects: tourism development has brought strong impacts on the environment as pollution of rivers, acoustics, aesthetics. Although among the most important impacts include loss of biodiversity and natural resource constraints which it is based on tourism. This overexploitation of resources has increased in recent years to unsustainable levels. Tourism can not function without the natural resource base on which it was built as its own environmental degradation directly affects its offer and may endanger the same tourist activity itself. Therefore various organizations and conventions (Agenda 21, UN) in recent years have realized the importance of conserving the natural environment to implement not only the touristy sector but all sectors of society to achieve sustainable development.
