Hey there!
We'll start with politics, and we'll use a pretty recent event.
Recently, President Trump declared Jerusalem as the capital of Isreal, and that started some tension between lots of people across the globe, and even some fighting and protest.
Environmental globalization could be the Paris Agreement.
Although our country is no longer globally involved, it still unites countries together around one central idea: we need to save the Earth.
We'll do cultural, next.
I'm gonna guess you've probably eaten Mexican food, or sushi, or anything from other countries.
That's globalization!
Immigrants came here to the melting pot of cultures, the United States of America, and shared their beliefs with all of us. We've sure altered their cuisine a little, but it's the same point.
I hope I helped!
