Nowadays, more and more people travel to other countries for holidays and work. Some people think that this increase in international travel is bad for the environment and it should be limited. I partly agree with this opinion.
On the one hand, I agree that international travel has a negative impact on the environment. Most international trips are made by plane, and planes produce a lot of carbon dioxide, which causes global warming. In addition, when many tourists visit a place, they create a lot of rubbish and use a lot of water and energy. For example, some beautiful beaches in Thailand had to close because too many tourists damaged the coral and the beach. Moreover, new hotels and airports are built in natural areas, and this destroys forests and the homes of animals.
On the other hand, I do not think that international travel should be strongly restricted. Firstly, tourism is very important for the economy of many countries, especially poor countries. Many people work in hotels, restaurants and travel companies, so if travel is restricted, they may lose their jobs. Secondly, travelling helps people learn about other cultures and become more open-minded. It is also important for business, because companies need to meet partners in other countries.
In my opinion, instead of restricting travel, governments should find ways to make travel more environmentally friendly. For example, they can put a tax on flights and use the money to protect the environment, and they can limit the number of tourists in some sensitive places.
In conclusion, I agree that international travel harms the environment, but I do not think it should be restricted too much, because it brings many benefits.
