1. conversion
of forests and woodlands to agricultural land to feed growing numbers
of people |
|
2. development
of cash crops and cattle ranching, both of which earn money for
tropical countries |
|
3. commercial
logging (which supplies the world market with woods such as meranti,
teak, mahogany and ebony) destroys trees as well as opening up forests
for agriculture |
|
4. felling of
trees for firewood and building material; the heavy lopping of foliage
for fodder; and heavy browsing of saplings by domestic animals like
goats. |
|
5. To compound
the problem, the poor soils of the humid tropics do not support
agriculture for long. Thus people are often forced to move on and
clear more forests in order to maintain production. |
