President Franklin Roosevelt called forests the “lungs of our land, purifying the air and giving fresh strength to our people.” Forests absorb potentially dangerous carbon dioxide while producing healthy oxygen. They trap dust, ash, pollen, and smoke, keeping them out of the air and our lungs. According to American Forests, a single tree can produce enough oxygen in one year to support two people, while absorbing 48 pounds of carbon dioxide and trapping ground-level ozone, carbon monoxide, sulfur dioxide, and other greenhouse gases.
