It’s hard to fully comprehend the world if you live your whole life in your hometown or country. You will never have the opportunity to witness the struggles, festivals, and customs of other nations.
You could argue that these things are shown to you by the media. However, while positive stories are often overlooked, the media frequently highlights a nation’s negative aspects. Consider the conflict in Syria and how you currently view the people and the country.
We are able to construct walls and barriers to comprehension thanks to the media. The only way to get around this is to explore the real world and see things for ourselves.
