TREES ... MANKIND’S FRIENDS

Trees have held an important place in man’s way of life since he has

been on the earth. Trees provided early man with weapons to defend

himself and helped provide him with food, shelter and fuel.

Trees have played an important role in the history of the United States.

Timber was our nation’s first export. The forest also provided our

forefathers with their homes, farm implements, rifle stocks and wagons.

The forest, by furnishing ties and utility poles, made possible the

expansion of railroad systems, electric power and telephone networks.

Every industry depends upon forest products in one way or another.

Trees are more important today than ever before. More than 10,000

products are reportedly made from trees. Through chemistry, the humble

woodpile is yielding chemicals, plastics and fabrics that were beyond

comprehension when an axe first felled a Texas tree.

The American standard of living depends to no small extent on the care

with which we use our forest resource. Fortunately, trees are a

renewable resource. They can be grown as a crop and harvested in such a

way that the stand is kept productive, and a steady supply of forest

products is assured.
