Tree Facts


Trees give us oxygen, and what is absolutely amazing is that while giving off oxygen, trees are absorbing carbon dioxide produced from the combustion of various fuels. Trees remove or trap lung-damaging dust, ash, pollen and smoke from the air, in addition to providing shade for people and conserving energy.


One tree that shades your home in the city will also save fossil fuel, cutting CO2 buildup as much as 15 forest trees.
 -National Arbor Day Foundation pamphlet #90980005

Planting trees remains one of the cheapest, most effective means of drawing excess CO2 from the atmosphere.
-Prow, Tina., The Power of Trees, Human Environmental Research Laboratory at University of Illinois.

A single mature tree can absorb carbon dioxide at a rate of 48 lbs./year and release enough oxygen back into the atmosphere to support 2 human beings.
-McAliney, Mike. Arguments for Land Conservation:Documentation and Information Sources for Land Resources Protection, Trust for Public Land, Sacramento, CA, December, 1993

Over a 50-year lifetime, a tree generates $31,250 worth of oxygen, provides $62,000 worth of air pollution control, recycles $37,500 worth of water, and controls $31,250 worth of soil erosion.
-USDA Forest Service Pamphlet #R1-92-100

If every American family planted just one tree, the amount of CO2 in the atmosphere would be reduced by one billion lbs annually. This is almost 5% of the amount that human activity pumps into the atmosphere each year.
-American Forestry Association Tree Facts: Growing Greener Cities, 1992
