- Actually I believe most of it is used for farming until the soil
- is depleted too much to continue growing food. The next piece of
- forest is then burned down. Most rain forest soil isn't actually
- all that good, and it doesn't take much to damage it.
-
- While "gone forever" isn't completely accurate, the forest isn't going
- to grow back on any reasonable human timescale. Plus many of the
- plants and animals will become extinct, so what does eventually grow
- back will not be thae same as what was originally destroyed.
