More About CO2
CO2 is a gas that is made when we breathe out. It is also made when we burn things like wood or gas. This gas is part of the air we share with all living things.
In our daily lives, we make CO2 when we cook or drive cars. Plants use this gas to grow and give us fresh air. This helps us stay healthy!
In the future, we can learn to make less CO2. This can help keep our Earth safe and cool. We can plant trees and use clean energy to help!
