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.
Marrisa lives in Alice Springs, Australia. This is her story.
"I am an indigenous Australian, which means I belong to a people who have been around for 50,000 years.
Aborigines are very proud of our country and I am very close to my native roots. It's very dry in the desert and looking for food when there is only sand can be very difficult.
We call food from the desert bushtucker. It's not always easy to find but I love going out bushtuckering.
My family are very important to me. I live with my cousins and there are more than 10 of us in my house.
I think family are important because they're always there for you when you are down and bring more happiness to your life.
I worry that in the future people are not going to be so close to their families anymore and that it will hurt some cultures.
One of the issues facing some children in my country is that their parents are on drugs and addictions are keeping them away from their children. Kids are abused and don't get looked after.
If I was in charge of the world I would change the way people connect with each other and socialise.
One way to stop wars is if people accept each other and accept that we are all different."
