It's pretty tough to describe all the things trees do for our environment. The shade that trees give can cool the surrounding area by almost 10 degrees. Their root systems hold together the forest floor and purify our drinking water. The trees themselves pull in carbon dioxide that we exhale, and produce the oxygen we inhale— air, clean air, that we all need to breathe. The forest provides habitat for thousands of different creatures, including a number of endangered species. Each does their part to continue the forest life cycle. Professional Foresters understand the complexity of ecosystems and are committed to maintaining balanced forests.
