Globalization is when something (like an industry or a business) is joined together between different countries. This means that people in different countries can work together and countries can share resources. The idea behind globalization is that it helps make the world a better and more fair place.
But there are some criticisms of globalization. Some people think that when a country joins in with globalization, they give too much power to a few big companies. These big companies can take advantage of people and countries, and it can sometimes hurt small businesses who don't have the same resources. Also, some people think that globalization means that people don't get paid fair wages for the work that they do, so it can take away some of their rights. Finally, different countries can have different laws, so it can be hard to make sure everyone is following the same rules.
