Trees are a renewable resource, where most other
substitutes are not.
Trees help supply the oxygen which we need to breathe.
Yearly, every acre of young trees can produce enough oxygen to keep 18
people alive. One mature, thriving tree, in one growing season, will
provide enough oxygen (450 pounds) to keep one man breathing for one year.
Fifty full-sized thriving trees are required to supply the annual oxygen
demand of one automobile.
On a good summer "growing" day with
temperatures of 80 degrees or higher, one large maple tree may transpire
as much as 150 gallons of water - pure, unpolluted water.
Trees help keep our air supply fresh by using up
carbon dioxide that we exhale and that factories and engines emit. An
automobile puts its weight in carbon into the air each year. Trees use
their hairy leaf surfaces to trap and filter out ash, dust, and pollen
particles carried in the air.
One acre of trees can remove approximately 13 tons of
dust and gases from the air each season.
Trees can be used to indicate air pollution levels of
sulfur dioxide, just as canaries were once used to detect dangerous
methane gas in coal mines. Sulfur dioxide plus rainfall equals acid rain (Sulphuric
Acid).
A healthy growing forest, while growing one pound of
wood, will remove from the atmosphere 112 pounds of carbon dioxide (and
other toxic gases) and release back to the atmosphere just over one pound
of oxygen.
One moderate sized tree has as much cooling effect in
a city as 20 average room air-conditioners running 20 hours per day.
Shade trees are "air conditioners" that make
no demand on your electric power. Shade trees can cool your home by as
much as 12 degrees on a hot summer day, thus saving energy.
Trees lower air temperatures by enlisting the sun's
energy to evaporate water in the leaves. There may be 12 degrees
difference between the temperature in the woods and outside the woods.
Trees provide food and shelter for many birds and wild
animals.

Trees give us a constant supply of products: plywood,
paper, furniture. railroad ties, and telephone poles are some of the most
obvious products, but trees are also used for things such as chocolate,
tea, coffee. cashews, rubber, fruit, nuts, cork and olives. Wood
derivatives are used in plastics, alcohol. film, medicines, ink, soap,
paint, shoe polish, perfume, deodorant, linoleum, cellophane, rayon and
much, much more.
Trees cut noise pollution by acting as barriers to
sound. Each 100 foot width of trees can absorb about six to eight decibels
of sound intensity. Along busy highways, which can generate as much as 72
decibels. this reduction would be welcome to residents.
Trees slow down forceful winds that often cause soil
erosion.
Tree leaves break the onslaught of pelting raindrops
on the soil surface, which gives the soil a chance to soak up as much
water as possible, and helps prevent soil erosion.
Tree roots hold the soil and keep silt from washing
into our streams.
Tree leaves, by decaying, replace minerals in the soil
and enrich it to support later plant growth.
Trees beautify the landscape with pleasing shapes and
patterns, fragrant blossoms and, in the fall, every color imaginable.
Trees beautify our gardens and grace our backyards,
thus increasing the value of our property.
Trees help provide for America's economic growth and
stability.
There are 760 million acres of forests in the United
States. Roughly, one acre in three of our land surface is forested.
Two-thirds of this, or 510 million acres, is suitable and available for
growing and harvesting timber. This is called commercial forest land.
People say. "What can I do - I'm only one
person!" This great country is made up of "one persons"! If
you could do only one thing for the environment, plant a tree, or as many
trees as you can, each year. You can encourage others to plant trees as
well.
