On Forests and Wood
Throughout the whole history of mankind wood has been one of man’s most valuable natural resources. Being an easily available material wood has been used in a wide variety of applications.
Even in the rapidly changing world of today, wood and wood products continue to serve mankind in thousands of ways. Of all our natural resources wood is the only one which is capable of reproducing itself in a relatively short time period – a condition which makes wood one of our most valuable materials. All of those who deal with wood must have a good knowledge of this material and the ways in which it can serve the man.
If forests, trees and wood disappeared suddenly, life would change greatly. Having a great number of artificial materials at our disposal we still depend on forests and forest products. How would our houses be furnished without lumber and veneer? If there were no forests, millions of people would never enjoy a good rest in the shadow of trees. If wood suddenly disappeared, we should not receive newspapers, our most important source of political, cultural and scientific information.
But for the forests the economy would be changed considerably. The forests and forest industry provide jobs directly or indirectly to millions of people. Many of the products we produce today cannot be duplicated by any other material and those which can be duplicated often lack the best qualities of wood.
Why is wood such an important material? The answer lies in the structure and composition of wood. The cellular structure gives wood high strength and makes wood very adaptable for cutting and shaping.
There are hundreds of species among softwoods and hardwoods. The wood of different species possesses numerous valuable properties such as high durability, attractive colour and pleasant odour. With proper management and utilization our forests can provide us with wood for a very long period of time. Wood will
