Hey there little buddy! Do you know what borders are? They are the imaginary lines or shapes around countries that tell you where one country ends and the other begins. Borders are important because they help keep people and things safe and organized.
Now, open borders mean that there isn't a strict boundary between two countries. It's like having an invisible doorway between two houses, where anybody can walk in and out without any restrictions. Open borders usually mean that people from one country can come and go to another country with very little or no restrictions like passport, visa or legal paperwork.
Some people think open borders are a good thing because it means that people from different countries can easily visit one another, do business, or work without much hassle. But there are others who think that open borders are not good because it can increase the risks in terms of security and resources for a particular country.
Imagine if your family had an open door with next-door neighbors, and people were free to go in and out of each other's houses. While it would be great to play with your friends and share toys, there could be times when a stranger might come in and steal something or cause trouble. That's why some people think open borders can be risky for countries when it comes to security risks.
In short, open borders mean that people can move between countries without too many restrictions. While it can be good for making friends and doing business, it can also come with risks when it comes to safety and resources of a particular country.
