"It is not easy to see how the more extreme forms of nationalism can long survive when men have seen the Earth in its true perspective as a single small globe against the stars"

This quote by Arthur C. Clarke speaks with the concept that severe forms of nationalism are unsustainable in the long-term. By viewing the Earth from a larger point of view, we can see that it is a small planet in the vastness of the universe. This awareness can help us to understand that we are all part of an international community, which extreme kinds of nationalism are not just not practical, but likewise damaging to our cumulative well-being. Nationalism can be a powerful force for excellent, but when it is taken to an extreme, it can lead to dispute and suffering. By understanding the Earth in its real viewpoint, we can acknowledge the significance of interacting to create a much better future for all.
