When an area starts being visited by tourists, there are bound to be some social and cultural impacts of those tourists on the host community. Locals may see increased congestion and overcrowding in towns and cities, perhaps an increase in crime, the introduction of new languages and values, and perhaps even an influx of migrant workers to be employed in the tourist industry. Socio-cultural sustainability, then, means minimizing these negative impacts and focusing on more positive ones, such as promoting cultural exchange and preserving local traditions. This can usually be achieved by getting the locals involved in the tourism industry. Having the community involved will not only offer visitors a more genuine experience, but the locals will be more likely to see tourism in a positive light because they will be proud of it.
