International alert is when different countries work together to make sure that everybody is safe and happy. It's like when you and your friends make sure that everyone is okay on the playground. But instead of just one group, it's many countries all over the world who work together to make the world a better place.
Sometimes things happen in one country that affect other countries too, like a big storm or a sickness. International alert means that people from different countries talk to each other and figure out how to help each other out. They might send supplies, like food and medicine, to the place that needs help. Or they might send people to help clean up after a disaster or to treat sick people.
International alert is also important for making sure that everyone is treated fairly and with respect. Sometimes people in one country are not treated kindly because of their skin color, religion, or where they come from. With international alert, people from all over the world work together to make sure that nobody is mistreated, and everyone has the same opportunities.
Overall, international alert means that people from all over the world are being friends and taking care of each other, just like you and your friends on the playground.
