Social networking sites encourage people to be more public about their personal lives. Because intimate details of our lives can be posted so easily, users are prone to bypass the filters they might normally employ when talking about their private lives. What's more, the things they post remain available indefinitely. While at one moment a photo of friends doing shots at a party may seem harmless, the image may appear less attractive in the context of an employer doing a background check. While most sites allow their users to control who sees the things they've posted, such limitations are often forgotten, can be difficult to control or don't work as well as advertised.
Successful tourism relies on establishing a basic infrastructure, such as roads, visitor centers and hotels. The cost of this usually falls on the government, so it has to come out of tax revenues. Jobs created by tourism are often seasonal and poorly paid, yet tourism can push up local property prices and the cost of goods and services. Money generated by tourism does not always benefit the local community, as some of it leaks out to huge international companies, such as hotel chains. Destinations dependent on tourism can be adversely affected by events such as terrorism, natural disasters and economic recession.
