FORESTS OF THE TROPICS . 



4. , .,i_. . — 4. 



The history of every counlry in the 

 process of development shows that ex- 

 cessive waste accompanies the exploit- 

 ation of its natural resources. Primi- 

 tive people of the tropics, by cutting 

 and burning the virgin forest areas to 

 practice a shifting system of agricul- 

 ture, have in the past been the great- 

 est enemies of tropical forests. Thus 

 two-thirds of the area of the original 

 forest of the Philippines disappeared 

 before the remainder was brought 

 under forest management. The virgin 

 forest area of countries of Central 

 America and the West Indies had 

 either been completely destroyed or 

 badly damaged. 



In temperate countries excessive 

 waste has been the rule everywdiere 

 until proper forest policies checked 

 such waste. 



The economic development of the 

 tropics will be greatly aided by the 

 avoidance of the mistakes made in 

 handling the forest resources of tem- 

 perate regions. This can be done only 

 by the adoption of a suitable forest 

 policy during the early stages of ex- 

 ploitation. 



What is Needed 

 What is needed is public apprecia- 

 tion of the value of the undeveloped 

 forest resources and of the possibility 

 of making them a permanent asset. 

 This can be brought about by expert 

 foresters who will not only direct 

 operations in the woods but also 

 arouse the public to the need of forest 

 conservation, and assist in the for- 

 mulating of a proper forest policy and 

 in the enactment and enforcement of 

 suitable legislation.— lV//e/^on's/Sc/ioo/
