Newsround has been taking a special look at the world you're growing up in.
We've been chatting to seven kids from around the world - one from each of the seven continents.
They're sharing their hopes and fears, and telling you about their lives.
Felipe, 12, lives in the American city of Chicago. This is his story.
"My mum and my Dad moved to the US from Mexico - a poor country in Central America.
They have worked hard to give us a good life. My family are the most important thing to me and I want them to be proud of me.
My neighbourhood is peaceful and I'm glad that I don't have to worry about crime. I love reading and studying a lot as well as playing computer games.
I love playing basketball most of all. I'm having try-outs for my school team the Visitation Vikings. I train up to three times a week and I just hope that I can make the team.
The thing that worries children like me the most is whether our education is good enough. We worry that we won't be able to get a good job or go to university after we finish school.
I want to do really well when I'm older and don't won't to struggle with money. I feel under a lot of pressure.
If I was in charge of the world I would try and get rid of poverty. I think the US government is doing as well as it can to help poorer countries but every country needs to work harder to get rid of poverty.
Maybe instead of using so much oil we could give it to poorer countries. If would be good if poor countries were given the help they need to build their own schools and hospitals."
