No Littering O-Zone: How Rising Ozone Levels Affect Tree Growth
In recent years, humans have been burning more and more fossil fuels. Fossil fuels are oil, natural gas, and coal. One of the extra products created by burning fossil fuels is ozone. Since the level of ozone is rising, the scientists wanted to know how this affects how trees grow. Tree growth starts in leaves. Therefore, scientists started by looking at the leaves. They looked at how many leaves were produced and the amount of nutrients in the leaves.

About Investi-gator
The Investi-gator is another member of the Natural Inquirer family. The Natural Inquirer, for middle school students, and the Investi-gator, for upper elementary students, present science the way scientists most often share their research with each other. That process is the written scientific paper. Each Investi-gator article presents research conducted by Forest Service scientists and their cooperators. All the research in the Investi-gator is concerned with nature or with society’s relationship to nature.
