International travel has been a contentious matter for a long time. It is believed that such travel can pose a threat to the environment and ought to have stricter boundaries to minimise environmental harm. In this essay, I will discuss several key reasons as to why I wholeheartedly agree with the proposal.
One major drawback of international travel is human behaviour. This is a result of their carelessness, because few individuals behave responsibly during their trips. Unfortunately, most people usually do not pay attention to global problems. Therefore, travellers fail to protect the habitats they visit. For example, on beaches visitors often drink beverages, and they are too lazy to throw bottles and cans in the trash. In addition, children may forget their toys, then their items are found in seas and oceans, which leads to water pollution.
Another significant reason is air contamination. Today, planes use petroleum-based fuel rather than alternative energy sources. Humanity has not yet invented aircraft that can fly in a less polluted way. Due to the large number of flights, the air is becoming increasingly not clean enough to live in and breathe fully. As a consequence, people suffer from dreadful long-related diseases, such as cancer.
To sum up, I assert that international travel entails considerable environmental damages. My firm conviction is that this is a sensible notion on the grounds mentioned above.
