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.
