Tourism can be sustainable...so that potential______(2 words) on the host community do not surpass the financial benefits.

Tourism can bring many economic and social benefits, particularly in rural areas and developing countries. Tourism can be sustainable if it is carefully managed so that potential negative effects on the host community do not surpass the financial benefits.
   Tourism creates jobs, both through direct employment within the tourism industry and indirectly in sectors such as retail and transportation. When these people spend their wages on goods and services, more jobs are created. The tourism industry also provides opportunities for small-scale businesses, which is especially important in rural communities, and generates extra tax revenues, such as airport and hotel taxes, which can be used for schools, housing and hospitals.
   Improvements to basic facilities also benefit the local community. Tourism encourages the preservation of traditional customs, folk music and festivals that might otherwise have been lost. Interchanges between hosts and guests create a better cultural understanding and can also help raise global awareness of issues such as poverty and human rights abuses.
   Tourism, particularly ecotourism, helps promote conservation of wildlife and natural resources such as rain forests, as these are now regarded as tourism assets. It also helps generate funding for maintaining animal preserves and marine parks through entrance charges and guide fees. By creating alternative sources of employment, tourism reduces problems such as over-fishing and deforestation in developing nations.
