Travel can help promote understanding and communication between countries by broadening one's horizons and knowledge of other cultures, lifestyles, and habits. It allows people to make friends abroad who can help them and take care of them, learn new languages, and gain a better understanding of other countries to reduce misunderstandings. Staying at home does not provide the same opportunities to become acquainted with other places as traveling does, which can be a very good learning experience that enhances understanding between nations.
