Increasingly,the development of tourism is seen to have an effect on the environment.Erosion ( 腐蚀 ),is one problem.The steps and stones of many popular sites like Shakespears’s birthplace or Stonehenge are literally being own away by millions of foreign feet.The remedy in the case of Britain’s best-known prehistoric monument has been to use railings to keep visitors at a distance,however,where tourist want to enter the actual building.
Overcrowding in cities is another problem Traffic jams are outcome.In narrow roads,tourists vehicles cause congestion ( 堵塞 ).Local traders and residents cannot get around to do their work.Car parks fill up,so strangers park where they can; in streets ,across getaways,or in private driveways.This causes obstruction.Thus Venice,a city built for half million people,is swollen by another half million who populate the city daily in the tourist season --- eight million visits each year.The mayor recently decided to limit visits to 90,000 a day.
Pollution is a further result.The lakes are popular for people who enjoy water sports ,such as water skiing,power boat racing and swimming,but boat pump sewage directly into the water .Facilities can be used to prevent this happening,but this is costly.There are also problem with litter.
The threat to wild life habitats is yet another result.Tourists around the lakes destroy vegetation.( 植被 ) This is harmful to animals,which build their nests along the shores.Wildlife refuges have been created to protect these natural sites,but they have been attacked by angry owners of hotels who make lucrative profits form bars or renting sun-bed and umbrellas.
