     People travel for a lot of reasons. Some tourists go to see battlefields or religious shrines.

Others are looking for culture, or simply want to have their picture taken in front of famous

places. But most European tourists are looking for a sunny beach to lie on.

     Northern European are willing to pay a lot of money and put up with a lot of inconveniences

for the sun because they have so little of it. Residents of cities like London, Copenhagen, and

Amsterdam spend a lot of their winter in the dark because the days are so short, and much

of the rest of the year in the rain. This is the reason the Mediterranean has always attracted

them. Every summer, more than 25 million people travel to Mediterranean resort and beaches

for their vacation. They all come for the same reason: sun!

     The huge crowds mean lots of money for the economies of Mediterranean countries. Italy's

30,000 hotels are booked solid every summer. And 13 million people camp out on French

beaches, parks and roadsides. Spain's long sandy coastline attracts more people than anywhere

else. 37 million tourists visit yearly, or_one_tourist_for_every_person_living_in_Spain.

     But there are signs that the area is getting more tourism than it can handle. The Mediterranean

is already one of the most polluted seas on earth. And with increased tourism, it's getting worse.

The French can't figure out what to do with all the garbage left by campers around St. Tropez.

And in many places, swimming is dangerous because of pollution.

     None of this, however, is spoiling anyone's fun. The Mediterranean gets more popular every

year with tourists. Obviously, they don't go there for clean water and solitude. They tolerate traffic

jams and seem to like crowded beaches. They don't even mind the pollution. No matter how dirty

the water is, the coastline still looks beautiful. And as long as the sun shines, it's still better than

sitting in the cold rain in Berlin, London, or Oslo.
