【单选题】

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 mostEuropean tourists are looking for a sunny beach to lie on.

(77) NorthernEuropeans 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, andAmsterdam spend a lot of their winter in the dark because the days are so short, and much of the rest of the year is 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.
(78) 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 sit- ting in the cold rain inBerlin, London, or Oslo.
