Tourism has a great number of demerits which will be discussed in more details. The most important demerit is that tourist sites could be polluted because of a great deal of garbage produced and thrown away by tourists. This will likely to have a detrimental imapct on the animals and vegetation which live in that region. An interesting example is that the forest located in northern part of Iran damaged by loads of plastic rubbish ,which cannot be recycled by the nature for decades, thrown away intentionally or unintentionally by foreginers. Another important demerit is that foreigners could possibly be a menace to the national security of the host country.They, for example, can conduct deliberate terrorist actions in the target country’s earth. A good analogy is a bomb detonated by two Indians in London tube on the 12th of August,2013 which killed two people and injured thousands of inocent people.

However, tourism has its own plus points as well which cannot go unseen. The most important plus point is tourists spends a significant amount of money purchasing foods, reserving flight tickets and luxurios hotels so that it would stimulate economic growth of host country. Retailers, for example,could sell their commodities to foreigners, and travel agencies can arrange compound trips to many exotic places in host countries, so these professions can make a lot of money through tourism. Again, tourists might experience a new tradition which can be totally different from their own countries’ cultures. A good example is foreign tourists who come to Iran would probably be surprised by dress code in this country, but they learn about Iranian culture and respect Islamic laws, though it might cotradict with their beliefs.
