Firstly, together with the well-done works of travel agencies, the spreading of the pictures and videos on social network enables people’s awareness about breathtaking views and interesting cultures from many countries across the world. Consequently, this reward has triggered the demand of travelling abroad. Secondly, many nations have adjusted their policy such as removing migration ban or passing less strictly regulations in order to encourage international free trading as well as widen co-operations in technology and education.At the other end of the spectrum, many people and third parties are expressing their concerns about the trend above’s pros and cons. Looking on the bright side, this development offers invaluable opportunities for local countries to strengthen their economic health and narrow the gap to worldwide civilization. By contrast, it is undeniable that increasing travel abroad brings with it environmental issues and negative impacts to local culture. For example, tourists are more likely to litter in holiday destinations where do not have alert boards or criminal fines.In conclusion, though the international process and hi-tech are have been resulting a significant rise of travelling oversea, I do believe that every country and other counterparts must take into accounts all the benefits and drawbacks to issue agreements for sustainable development.
