Visiting other countries is fantastic and favorable. The visit, gratifyingly, has become more easier for people, whether it is because of the simplified procedures like the visa-free scheme or the lower expense. 

[概括观点] Being dropped into a new country can expand the visitor’s perspective.[解释观点] Suddenly, one has to order meals in a new language, navigate unfamiliar places, and cope with unexpected dilemma, through which he could realize how resourceful and capable he could be. Educational as these unforgettable novelties are, they, different from what the visitors have known, could also teach them to be tolerant, appreciating these differences. [概括观点] For the destination, the more outboard visitors, the better preservation of its culture. [解释观点]  To specify, having plumbed that people come for new things, local government would try its best to prevent culture from fading away. This way, cultural diversity is guaranteed.

[适度的转折]Indeed, this is not the whole story.[解释观点]A deluge of visitors can bedevastating to local environment, as they may litter everywhere and mark the facilities. [举例证实] As a matter of fact, even the relatively most inaccessible scenic spots, the Mount Everest, for example, have not escaped human-generated waste. [对应着驳倒] However, I personally think such an ongoing plight can and is being changed, thanks to the booming tourism. [解释理由] This is because more and more authorities have realized that the sustainable tourismhinges largely on a neat and tidy environment, so how could anyone of them fail to clean thegarbage-engulfed corners and repair damaged facilities?
