Why is learning about people in the global community important?

I think it is important because we need to have good relationships with different countries and people. I think it will be great if we could learn how to speak other countries languages. It’s also important to learn about people in our global community so that we know whats wrong and whats good like for instance if we were in a Samoan church and we started to text or to start eating in the church that wouldn't be the right thing to do .
