Forests are like big, green lungs that help people breathe by taking in carbon dioxide and giving out oxygen. Trees do this all day long through a process called photosynthesis. In cities, there are lots of buildings, cars, and machines that burn fuel, which gives off more carbon dioxide, making the air feel stuffy.
Examples
- A forest takes in a lot of carbon dioxide like it’s drinking water. A city produces more than it absorbs, like a soda can that keeps bursting.
- In a city, every time you start your car, it releases more carbon dioxide into the air, but in a forest, trees quietly take some of it back.
