Balancing Act: Urban Trees and the Carbon Cycle
Too much carbon dioxide (CO2) in the atmosphere is mostly caused by two things: burning fossil fuels and the loss of trees. Urban trees help to keep urban areas cooler, they hold soil in place, they make urban areas prettier, and they help to keep urban areas quieter. They also absorb CO2 from cars, buses, and the many engines that are used in urban areas. When people plant and maintain urban trees, they usually use machines with engines which emit CO2. When a tree is cared for using machines with engines, there is a point in the tree’s lifetime at which more CO2 will be emitted from the engines than the tree has absorbed. The scientists wanted to know which tree species can grow the longest before reaching that point.

Note To Educators
The Forest Service's Mission
The Forest Service’s mission is to sustain the health, diversity, and productivity of the Nation’s forests and grasslands to meet the needs of present and future generations. For more than 100 years, our motto has been “caring for the land and serving people.” The Forest Service, an agency of the U.S. Department of Agriculture (USDA), recognizes its responsibility to be engaged in efforts to connect youth to nature and to promote the development of science-based conservation education programs and materials nationwide.
What Is the Natural Inquirer?
Natural Inquirer is a science education resource journal to be used by students in grade 6 and up. Natural Inquirer contains articles describing environmental and natural resource research conducted by Forest Service scientists and their cooperators. These scientific journal articles have been reformatted to meet the needs of middle school students. The articles are easy to understand, are aesthetically pleasing to the eye, contain glossaries, and include hands-on activities. The goal of Natural Inquirer is to stimulate critical reading and thinking about scientific inquiry and investigation while teaching about ecology, the natural environment, and natural resources.
