With the development of transportation, international travel is becoming easier, faster and cheaper for many people nowadays. However, every coin has two sides, and it is also the same with international travel.
For one thing, international travel is a good thing both for travelers and for the countries they visit generally. It gives travelers a chance to visit other places, gain new experience and admire famous historical sights and beautiful natural scenery. It is also good for the tourism of the countries, which may bring a lot of economic benefit for the countries. However, we can’t ignore the negative side of international travel. Flying, cruising, eating out, and driving around all have a negative impact on the environment. Most people when they travel constantly use towels in hotel rooms, leave the air conditioner on, or forget to turn off the lights. And in some cases, not all tourists have a good attitude and manners to the local people.
To conclude, international travel is a great thing, but it is a privilege that should not be abused. Governments should encourage it, but also put in place measures to keep dangerous people away. This will result in a win-win situation for everyone.
