Most countries in the world now welcome tourists because of the money they bring in. Many

countries make great efforts to encourage tourism, and many also depend on what they earn from it to keep their economies going.

People who like adventure will even try to visit countries where travel is difficult and costs are high. Companies regularly arrange trips throughout the Sahara desert, or to the Himalayan Mountains for whoever enjoys such trips, but the numbers of visitors are small. Most tourists try to choose whichever places have fairly comfortable, cheap hotels, quite good food, reasonable safety, sunny weather and plenty of amusements or unusual things to see. Their choice of a place for a holiday also depends very much on when they can get away; it is not very pleasant to go to a place when it is having its worst weather.

One of the big problems for a nation wishing to attract a lot of tourists is the cost of building hotels for them. Building big hotels swallows up a lot of money, and many of the countries that need the tourists are poor. What they spend on building has to be borrowed from foreign banks. And sometimes the money they can afford to borrow produces only chains of ugly hotels wherever there are beauty spots that are supposed to attract the tourists.

Another problem is that more and more big international companies are building hotels all over the world, so that the profits from a hotel often do not stay in the country in which it has been built. And there is also the question of training staff; teaching them foreign languages, how to cook the kind of food that the foreign tourists expect, and so on. In many countries, special colleges and courses have been set up for this.

Crime can also be a problem. Seeing tourists who seem to be much richer than them selves, the local inhabitants are often tempted to stem from them. Sometimes tourists resist and get killed, and then other tourists refuse to come to the country. But an even greater problem in many countries is the effect that the sight of foreigners has on the local population. A man who lives in a very small house, owns almost nothing, works very hard for his living and has very strong roles about modesty in dress and not drinking alcohol sees foreign tourists rejoicing in what to him is great luxury, owning radios, wearing very few clothes and drinking a lot of beer. These tourists may be ordinary workers back home, but to the poor inhabitant they seem to be very rich. And of course, he either feels envy for them or thinks them shameless.

Tourists, too, often feel shocked by the different customs and habits that they see around them. They refuse the local food, and insist on having only what they eat back home. They say that travel broadens the mind; but it is doubtful whether this is so, often, it narrows it.
